Answer:
the small one will have greater acceleration
Explanation:
force and mass are inversely proportional. force and acceleration are directly proportional. which means greater mass have smaller acceleration and smaller mass has greater acceleration. this is due to newtons second law of motion.
The small object will have greater acceleration as compared to a heavy truck if we push with the same amount of force, i.e., 7000 N.
What is acceleration?Acceleration is proportional to change in velocity.
When there will be a change in velocity with time, that is called acceleration.
[tex]\vec{a}[/tex]=[tex]\vec{dv}/dt[/tex] where,
[tex]\vec{a}[/tex] is the acceleration,
[tex]\vec{dv}[/tex] is the change in velocity and,
dt is change in time.
It is a vector quantity.
SI unit of acceleration is [tex]m/s^{2}[/tex].
There are several types of acceleration :
Uniform acceleration Non-Uniform accelerationInstantaneous acceleration.As we know that acceleration depends on the change in velocity and velocity of a body depends on the mass of the body. So if the body has less mass it must have a higher velocity and if it has a higher velocity than it has greater acceleration.
Hence, the small object/body has greater acceleration as compared to a heavy truck.

What types of evidence are used to support The Big Bang theory?
Answer:
Hubble's Discovery
cosmic microwave background radiation
Answer:
Three main pieces of evidence for the Big Bang theory are the red-shift of light, cosmic background radiation and types of elements.
Explanation:
Two major scientific discoveries provide strong support for the Big Bang theory: • Hubble's discovery in the 1920s of a relationship between a galaxy's distance from Earth and its speed; and • the discovery in the 1960s of cosmic microwave background radiation.
1. What was Swimmer C's average speed?
2. What was Swimmer A's average speed during the period 10 min to 20 min?
Answer:
4.8 km/hr ;
0
Explanation:
Based on information plotted on the graph :
Distance traveled by swimmer C = 2400 m
Travel time of swimmer C = 30 minutes
Converting distance to km:
2400 m = 2400 / 1000 = 2.4 km
Converting time to hour :
30 minutes = 30 / 60 = 0.5 hour
Average speed = Distance traveled / time taken
Average speed = 2.4 km / 0.5 hour = 4.8 km/hr
2.)
Swimmer A's average speed during the period 10 to 20 minutes ;
Change in distance /change in time
(400 - 400) / (20 - 10) = 0
Hence, distance traveled is 0

3. a) Your body is made up of several simple machines that help you move. Identify three
parts of your body that act as simple machines. Identify the kind of machine for each one
and explain what it does.
Answer:
Explained below
Explanation:
1) The human arm: This is a type of simple machine called "Lever". In this type of machine, the elbow acts as the fulcrum, the palm serves as the load because that's where we place the load we want to carry. While the inner part of the arm which is the inner part of the elbow represents the effort because that is the joint we mover when making use of our arms.
2) Pulleys: An example of this in the human body is the knee cap where the direction of an applied force is changed. Thus means as it is in motion, it alters the direction for which the quadriceps tendon pulls on the tibia.
3) wheel and axle: An example of this in the human body is the lateral rotation of the shoulder joint medial. The humerus which is the bone between the shoulder and elbow will act as the axle while the rotator will be the will because when it is rotated a little bit, the humerus will move along with it.

The three modified Atwood's machines shown below have blocks of mass M on a frictionless surface
and hanging from a string. When the blocks are released, they accelerate.
Rank them from smallest to largest and explain why in a short paragraph using the mass terms and force.
Answer:
Smallest - B
Largest - C
Middle - A
The hanging mass provides the force for accelerating the system.
In case A the force M G accelerates 2 * M
So you have for F = M a M * g = 2 * M * a or a = g / 2
In case B F = M a M * g = 3 * M * a and a = g / 3
In case C F = 2 * M * g 2 M * g = 3 * M * a and a = 2 * g / 3
Rank from smallest to largest force Smallest - B, Middle - A, Largest - C.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

The box is pushed to the right with a force of 40 Newtons and it just begins to move what is the maximum static frictional force
Answer:
The maximum static frictional force is 40N.
Explanation:
When an object of mass M is on a surface with a coefficient of static friction μ, there is a minimum force that you need to apply to the object in order to "break" the coefficient of static friction and be able to move the object (Called the threshold of motion, once the object is moving we have a coefficient of kinetic friction, which is smaller than the one for static friction).
This coefficient defines the maximum static friction force that we can have.
So if we apply a small force and we start to increase it, the static frictional force will be equal to our force until it reaches its maximum, and then we can move the object and now we will have frictional force.
In this case, we know that we apply a force of 40N and the object just starts to move.
Then we can assume that we are just at the point of transition between static frictional force and kinetic frictional force (the threshold of motion), thus, 40 N is the maximum of the static frictional force.

Roark saw Alejandro sitting by himself in the quad and leaning over, with his head resting on the heels of his hands. Roark approached him and said, "Hey Alejandro, you look sad." Alejandro responded, "Huh? No, I'm just thinking." Which difficulty in interpreting nonverbal behavior does this exchange exemplify?
A. Nonverbal messages are often ambiguous.
B. Nonverbal messages are continuous.
C. Nonverbal cues are multichanneled.
D. Nonverbal interpretation is culture-based.
Answer:
Option A
Explanation:
Nonverbal communications are ambiguous because some times the face expressions (non verbal signals – Sad face or sitting alone gesture of Alejandro) and the verbal signals (communication between Roark and Alejandro) do not match or contradict each other. Some people prefer to believe on their interpretations of the nonverbal signals as compared to that of the verbal signals
Hence, option A is correct.

Answer:
Distance = 84 meters
Explanation:
Given the following data;
Work done = 168,000 Joules
Force = 2,000 Newton
To find the distance covered by the automobile, we would use the formula;
[tex] Workdone = force * distance [/tex]
Substituting into the formula, we have;
[tex] 168000 = 2000 * distance [/tex]
[tex] Distance = \frac {168000}{2000} [/tex]
Distance = 84 meters

A mercury in barometer shows a height of 70cm.What height would be shown in the barometer at the same place if water density 1.0×10³kg/m³ is used(denssity of mercury=13600kgm-³)
Answer:
P = d g h pressure due to density of liquid of height h
d1 g h1 = d2 g h2 since P1 equals P2
d1 h1 = d2 h2 and the density of Hg is 13.6 times that of water
h2 = (d1 / d2) * h1 = 13.6 * 70 cm = 952 cm or 9.52 m

A 30.0 kg rock falls from a 35.0 m cliff. What is the kinetic and potential energy when the rock has fallen 12.0 m?
Answer:
When the rock has fallen 12.0 m;
The kinetic energy of the rock is approximately 3,531.6 J
The potential energy of the rock is approximately 6,768.9 J
Explanation:
The question relates to the characteristic constant total mechanical energy of a body
The mass of the rock that falls, m = 30.0 kg
The height of the cliff from which the rock falls, h₁ = 35.0 m
The required information = The kinetic and potential energy when the rock has falling 12.0 m
The kinetic energy is given by the formula, K.E. = 1/2×m×v²
The potential energy is given by the formula, P.E. = m·g·h
Where;
g = The acceleration due to gravity ≈ 9.81 m/s²
The velocity of the rock after falling through a given height, h is given by the formula, v² = 2·g·Δh
The total mechanical energy of the rock, M.E. = K.E. + P.E. = Constant
At the height of the cliff before falling, Δh =0, therefore v₁ = 0, therefore, K.E. = 1/2×m×v₁² = 0 J
The potential energy at the cliff before the rock begins to fall, P.E. is goven as follows;
P.E. = 30.0 kg × 35.0 m × 9.81 m/s² = 10,300.5 J
At the top of the cliff, M.E. = K.E. + P.E. = 0 J+ 10,300.5 J = 10,300.5 J
∴ M.E. = 10,300.5 J
When the rock has fallen, 12.0 m, Δh = 12.0 m, the speed of the rock, v₂, is given as follows;
v₂² = 2 × 9.81 m/s² × 12.0 m = 235.44 m²/s²
v₂ = √(235.44 m²/s²) ≈ 15.344 m/s
∴ When the rock has fallen 12.0 m, K.E., is given as follows;
K.E. = 1/2×m×v₂²
K.E. = 1/2 × 30.0 kg × 235.44 m²/s² = 3,531.6 J
When the rock has fallen 12.0 m the kinetic energy, K.E. = 3,531.6 J
When the rock has fallen 12.0 m, M.E. = P.E. + K.E.
M.E. = Constant = 10,300.5 J
K.E. = 3,531.6 J
∴ 10,300.5 J = P.E. + 3,531.6 J
P.E. = 10,300.5 J - 3,531.6 J = 6,768.9 J
∴ When the rock has fallen 12.0 m, the potential energy, P.E. = 6,768.9 J.

Are the number of atoms before and after a chemical reaction the same? Why?
Answer:
They rearrange themselves and join together differently to make new substances called products. The number of atoms of each type is the same before and after a reaction. This means that the total mass of the products is the same as the total mass of the starting substances. In other words, mass is conserved.
