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.
how can understanding velocity help to prevent a mid-air collision
Answer:
To maintain enough time to prevent a collision, a system operating in air traffic where aircraft speed does not
fall below 100 km/h (most medium-sized UAVs and GA aircraft) will need to be able to detect obstacles which
subtend an arc-width of as small as 0.125 mra

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.
A weightlifter lifts a set of weights a vertical distance of 2.0 m. If a constant net force of 350 N is exerted on the weights, what is the net work done on the weights?
Answer:
700 Joules
Explanation:
The work done equals force times distance. Just multiply your two values there.
Side note: It would be more impressive if he'd done it in 1 second rather than 5. You know why? Because POWER=WORK/TIME. The less time it takes him to lift the weight with the same force and distance, the more powerful he is!

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.

Empujamos un baúl 3 metros, para ello aplicamos una fuerza de 200 Newton. ¿Cuál es el trabajo realizado?
Answer:
Trabajo realizado = 600 Nm
Explanation:
Dados los siguientes datos;
Fuerza = 200 Newton
Distancia = 3 metros
Para encontrar el trabajo realizado; Trabajo realizado = fuerza * distancia
Sustituyendo en la ecuación, tenemos; Trabajo realizado = 200 * 3
Trabajo realizado = 600 Nm

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.
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.

a wagon of mass 42 kg is pushed by a student a distance of 12.2 meters, and 297 j of work was sone on the wagon how much force did the student apply assuming that it was constant
Answer:
Force=2.484 N
Explanation:
[tex]f = \frac{w}{gh} \\ = \frac{297}{9.8 \times 12.2} \\ f = 2.484 \: n [/tex]

PLS mark BRAINLIEST
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

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".
