For an object falling at the terminal velocity, list all the forces (magnitude and direction) acting it?
Answer:
Three stages of falling
There are three stages as an object falls through a fluid:
at the start, the object accelerates downwards due to the force of gravity
as the object's speed increases, frictional forces such as air resistance or drag increase
at terminal velocity, the weight of the object due to gravity is balanced by the frictional forces, and the resultant force is zero

In order to increase the final momentum of a golf ball, we could
a) follow through when hitting the ball
b) increase the force acting on it
c) increase the time of contact with the ball
d) swing as hard as possible
f) All of the above
Answer:
option f) all of the above
We will see that all of the given options would increase the momentum, so the correct option is f "all of the above"
How to increase the momentum?
Momentum is defined as the amount of motion, and it is given by:
P = m*v
Where m is the mass of the object and v is the velocity.
We can't change the mass of the golf ball, but we can change the velocity, and to do it, we need to increase the acceleration that we apply to the ball.
To increase the acceleration we can:
follow through when hitting the ball (the force is applied for more time, so the acceleration is larger).increase the force acting on it (it directly increases the acceleration).increase the time of contact with the ball (similar to the first option).swing as hard as possible (similar to the second option).Then all the options are correct, which means that the correct option is f.

Which of these statements is true about the effect of a force exerted upon an object?
a. A large force always produces a large change in the object's momentum.
b. A small force always produces a large change in the object's momentum.
c. A small force applied over a long time interval can produce a large change in the object's momentum.
d. A large force produces a large change in the object's momentum only if the force is applied over a very short time interval.
Answer:
d. A large force produces a large change in the object’s momentum only if the force is applied over a very short time interval.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
Also, the impulse of an object is given by the formula;
[tex] Impulse = force * time [/tex]
In accordance with the impulse-momentum theorem, the statement which is true about the effect of a force exerted upon an object is that a large force produces a large change in the object’s momentum only if the force is applied over a very short time interval.
A box of mass 5.0 kg is initially at rest. A 500 N force causes it to move horizontally through a
distance of 12.00 m. How much work would there be?
Answer:
Workdone = 6000Nm
Explanation:
Given the following data;
Mass = 5kg
Force = 500N
Distance = 12m
To find the work done;
Workdone = force * distance
Workdone = 500 * 12
Workdone = 6000Nm

Which of these is not a standard unit?
a. second
b. metre
c. hand span
d. gram
Answer: Hand span
Explanation: Hand span is not a standard unit.
Second is the unit of time.
Meter is the unit of length or distance covered by an object.
Gram is the unit of weight of an object.
Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".

What is the equation used to find the image distance? Identify each variable
Answer:i f I understand your question correctly, the formula is as follows:
Note: The sign convention is based on distances which are measured from the lens to the object or image of regard. Distances measured in the same direction the light is moving are positive and distances measured in the opposite direction the light is moving are negative.
The measurements are in meters
The “ambient” index of refraction is assumed to be n=1.00
The inverse of the object distance plus the dioptric power of the lens (convex—positive and concave—negative) equals the inverse of the image distance.
Or 1/Od +Dl =1/Id

How the choice of building materials and techniques can help them cool down faster, after heating up.
Answer:
The choice of building materials and techniques can help them cool down faster, after heating up is explained below in brief details.
Explanation:
Building materials
Buildings that are composed of rock, bricks, or pavement, or inserted into the territory, can seem cooler thanks to the great "thermal mass" of these elements – that is, their capability to assimilate and discharge heat gently, thereby softening temperatures over time, producing daytime cooler and night-time warmer.
What happens to the arrangement of atoms in matter as it is heated?
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance.

An automobile of mass 1.46 E3 kg rounds a curve of radius 25.0 m with a velocity of 15.0 m/s. The
centripetal force exerted on the automobile while rounding the curve is:
Answer:
Centripetal force = 13140 Newton.
Explanation:
Given the following data;
Mass = 1.46 E3 kg = 1.46*10³ = 1460 kg
Velocity = 15m/s
Radius, r = 25m
To find the centripetal force, we would use the following formula:
Centripetal force = mv²/r
Substituting into the equation, we have;
Centripetal force = (1460*15²)/25
Centripetal force = (1460 * 225)/25
Centripetal force = 328500/25
Centripetal force = 13140 Newton.

A wagon of mass 42 kg is pushed by a student a distance of 12.2 meters, and 297 j of work was done on the wagon force did the student apply is 24.34 N.
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.
work = force*distance
force = work/distance
force = 297/12.2
force = 24.34 N

A 0.144 kg baseball approaches a batter with a speed of 20m/s . The batter lines the ball directly back to the pitcher with a speed of 30m/s . Find the impulse exerted on the ball . If the bat and ball were in contact for 0.012 sec , find the average force exerted on the ball by the bat
Answer:
The impulse exerted by the ball is 7.2 kg.m/sThe average force exerted on the ball by the bat is 600 N.Explanation:
Given;
mass of the baseball, m = 0.144 kg
velocity of the baseball, v₁ = 20 m/s
velocity of the batter, v₂ = -30 m/s (opposite direction to the ball's speed)
The impulse exerted by the ball is calculated as follows;
J = ΔP = mv₁ - mv₂
ΔP = m(v₁ - v₂)
ΔP = 0.144 [20 - (-30)]
ΔP = 0.144 ( 20 + 30 )
ΔP = 0.144 (50)
ΔP = 7.2 kg.m/s
The average force exerted on the ball by the bat is calculated as;
[tex]F = \frac{\Delta P }{t} \\\\where; t \ is \ time \ of \ contact= 0.012 \ s\\\\F = \frac{7.2}{0.012} \\\\F = 600 \ N[/tex]

29. A wave source approaches your location, describe
the shift in wavelength and frequency you will
perceive.
Answer:
The waves travel at the same speed, but the observed frequency depends on any relative motion between the observer and source. When the observed frequency changes, so does the wavelength. If the observer and source are moving toward each other, then the frequency increases and the wavelength decreases.
