Answer: B
Explanation:
It will move slower than the light the object. The equation is Newton's 2nd Law of F = ma. If the force is constant, and the mass changes to something larger, then the acceleration must become smaller. You could also just do this yourself, push two objects with your hands. The heavier one will move slower assuming you used the same amount of force

For any object in motion, distance is always _________ displacement
Answer:
for any object in motion , distance is always greater than displacement
For any object in motion, distance is always greater or equal to the displacement but it can never be less than the displacement because displacement is the shortest distance measured between the initial and the final position.
What is displacement?An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard.
Displacement describes this shift in location.
Distance is always higher or equal to displacement for any item in motion, but it can never be less because displacement is the shortest distance between the beginning and end positions.

According to Mendel's law of segregation, what takes place during meiosis?A.Pairs of alleles cross over on chromosomes, exchanging one for anotherb.Pairs of alleles separate in meiosis, and each gamete receives one allele of a pairc.Part of an allele is separated, or broken off, from its chromosomed.One chromosome is suppressed, and the other chromosome of the pair determines the traits of the offspring
Answer:
b. Pairs of alleles separate in meiosis, and each gamete receives one allele of a pair.
Explanation:
Gregor Mendel, who is referred to as the FATHER OF GENETICS because of his contribution to the principles of inheritance, proposed in one of his laws called LAW OF SEGREGATION that the alleles of a gene will separate into gametes in such a way that only one of the two alleles that make up a gene will be in each gamete.
This division/separation of alleles during gamete formation is called MEIOSIS. Note that, allele is one member of a gene. Hence, according to Mendel, in meiosis, pairs of alleles separate and each gamete receives one allele of a pair.

A 5kg box rests on a table. a 3 kg box rests on top of the 5 kg box. what is the normal force from the table?
a. 19.6 n
b. 29.4 n
c. 49 n
d. 78.4 n
==> The total mass resting on the table is (5 kg + 3 kg) = 8 kg.
==> The total weight of that mass is (8 kg) x (9.8 m/s) = 78.4 newtons
==> The boxes are stacked. So the table doesn't know if the weight on it is coming from one box, 2 boxes, 3 boxes, or 100 boxes in a stack. The table only knows that there is a downward force of 78.4 newtons on it.
==> The table stands in a Physics classroom, and it soaks up everything it hears there. It knows that every action produces an equal and opposite reaction, and that forces always occur in pairs.
Ever since the day it was only a pile of lumber out behind the hardware store in the rain, the table has known that in order to maintain the good reputation of tables all over the world, it must resist the weight of anything placed upon it with an identical upward force. This is the normal thing for all good tables to do, up to the ultimate structural limit of their materials and construction, and it is known as the "normal force".
So the table in your question provides a normal force of 78.4 newtons. (d)
Engineers at the Space Centre must determine the net force needed for a rockets engine to achieve an acceleration of 70 m/s2. Assume the rocket is in outer space with no gravitational or other forces acting on it. If the mass of the rocket is 45 000 kg, what force is required to be produced by the rocket engines?
Answer:
3,150,000N
Explanation:
According to Newton's second law;
F = mass * acceleration
Given
Mass = 45000kg
acceleration = 70m/s^2
Substitute
F = 45000 * 70
F = 3,150,000N
Hence the force required to be produced by the rocket engines is 3,150,000N
Answer:
3,150,000 Newtons
Explanation:
F=M*A
F=45,000kg times (*) 70 m/s squared
F=3,150,000N (newtons)
The specific heat capacity of copper is 390 J/Kg AC. What does this
mean?
Answer:
It means that 400 J of heat is the required amount to raise or lower thh temperature of a 1kg piece of copper
Explanation:
390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C
From the given information,
The specific heat capacity of copper is 390 J/Kg °C. To determine what this means, we will define the term specific heat capacity.
The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1 °C.
Therefore, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.
Hence, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.

А
Heat transfer between the two things stops
B
Their molecules stop moving
They have the same number of molecules
D
Their molecules move at the same average speed
Answer:
When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects.
tony walks at an average speed of 70 m/min from his home to his school.If the distance between his home and the school is 2100 , how much time does it take for tony to walk to school
It takes 30 minutes for Tony to get to school.
2100 divided by 70 is 30, which would represent the amount of minutes.
Also he is walking very fast to be getting 70 in a minute.

A 4.0 kg box is released from rest on a frictionless ramp. The box slides from the ramp onto a rough horizontal
surface with a friction coefficient per = 0.50. The box slides 2.0 m horizontally until it stops.
Answer:
0.99932188871837 rounded to 2 significant figures is 1.00m or 1.0m
Explanation:
Step 1 - First calculate the force with the formula: Force = mass × acceleration due to gravity/ (F=mg) {g= 9.8m/s²}
4.0kg × 9.8m/s² = 39.2 Newtons
Step 2 - Then calculate the Kinectic power with the following procedure:
Kinectic force = the coefficient of Kf × mg
0.50μ × 39.2 N = 19.6 Newtons of Kinectic force
Step 3 - Use the equation for Work that is = F×d; use the value of Kf and multiply it by the given distance
W = 19.6 N × 2.0m = 39.2 Joules of energy
↓Remember that the product of Work is Energy (W=E) and that in some cases, we can set W as = kinetic energy ( [tex]\frac{1}{2}[/tex]mass×velocity²) or as = gravitational potential energy (mass *acceleration due to gravity*height)
↑Since the unknown variable that we are told to find is 'height', let's use the second formula to help us solve the problem, where we said that GPE = mgh / PEg = mgh
Step 4 - Find the missing height using the formula, Energy gained from (W = mgh), by rewriting (mgh) to solve for h
39.2 J of E = 4.0kg × (9.8 m/s² × h)
h = [tex]\frac{PEg}{mg}[/tex]
h = [tex]\frac{39.2N}{9.8m/s{2} times 4.0kg}[/tex]
Height of box on-ramp = 1.0m
convert 35 km/h to m/s

a ball of mass 1kg is being suspended 10m above the ground & is then dropped. what is the balls kinetic energy just before it hits that ground ?
a. 10 J
b. 98 J
c. 50 J
d. 0 J
Answer:
E = 98 J
Explanation:
Given that,
The mass of a ball, m = 1 kg
It is being suspended 10m above the ground & is then dropped.
We need to find the ball's kinetic energy just before it hits that ground. The conservation of energy holds here. It means, the kinetic energy just before it hits that ground is equal to its potential energy i.e.
[tex]E=mgh\\\\E=1\times 10\times 9.8\\\\E=98\ J[/tex]
so, the required energy is 98 J. Hence, the correct option is (b) "98 J".

What is the momentum of a 1, 500 kg car traveling at 3m/s?
67,500 kgm/s
67.5 kgm/s
4.5 kgm/s
4,500 kgm/s
========================================
Work Shown:
To find the momentum, we multiply the mass and the velocity.
m = mass = 1500 kg
v = velocity = 3 m/s
p = momentum
p = m*v
p = (1500 kg)*(3 m/s)
p = (1500*3) kg m/s
p = 4500 kg m/s
The momentum of an object is the product of its mass and velocity. Thus momentum of the car with 1500 kg and velocity of 3 m/s is 4500 kg m/s.
What is momentum?Momentum is a physical quantity that measure the ability to keep the force which make an object moves faster. Momentum like force is a vector quantity and is characterized with magnitude and direction.
Momentum is the product of velocity and its mass. Hence as the mass or velocity increases, momentum also increases. Increase in momentum makes the object moves faster.
Given mass of car = 1500 Kg
velocity = 3 m/s
momentum = velocity × mass
= 1500 Kg × 3 m/s
= 4500 Kg m/s.
Therefore, the momentum of the car is 4500 kg m/s.
