Explain the difference between the direction of force and the plane of application of force. Use a diagram to help you.
The direction of force refers to the path along which the force acts. The plane of application of force, on the other hand, is the surface or area where the force is applied
What is the difference between the direction of force and the plane of application of force?The direction of force refers to the path along which the force acts. It is the straight line in which the force is being applied. For example, if you push a box on the ground, the direction of force is the line of action of the force vector that points in the direction of the push.
The plane of application of force is the surface or area where the force is applied.

Work is being done when
Answer:
To express this concept mathematically, the work W is equal to the force f times the distanced, or W = fd. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
The SI unit of work is the joule (J). It is defined as the work done by a force of one newton through a distance of one meter.
Explanation:
Work is done when a force is applied to an object through a distance. This means that when a force is applied to an object through a distance, the object's total energy will be affected.
A Ball A and a Ball B collide elastically. The initial momentum of Ball A is 14.0kgm/s and the initial momentum of Ball B is -9.00kgm/s. Ball A has a mass of 2.00kg and is traveling at -5.00 m/s after the collision. What is the velocity of ball B if it has a mass of 3.00kg
The total momentum before collision is
14.0 kg•m/s + (-9.00 kg•m/s) = 5.00 kg•m/s
If v is the velocity of ball B after colliding with ball A, the total momentum after collision is
(2.00 kg) (-5.00 m/s) + (3.00 kg) v
Momentum is conserved, so these quantities are equal. Solve for v :
5.00 kg•m/s = (2.00 kg) (-5.0 m/s) + (3.00 kg) v
5.00 kg•m/s = -10.0 kg•m/s + (3.00 kg) v
15.0 kg•m/s = (3.00 kg) v
v = (15.0 kg•m/s) / (3.00 kg) = 5.00 m/s
1. The distance between a trough and a crest on a transverse wave is 12.0cm. If cycles of the wave pass a fixed point in one second, calculate the speed of the wave.
Answer:
0.12m/s
Explanation:
v=λf
Given that, λ = 12cm = 0.12m
T = 1second
(A period T is the time required for one complete cycle of vibration to pass a given point)
frequency 'f' is unknown but we can get frequency from f = 1/T = 1/1 = 1Hz
therefore, v= 0.12 × 1 = 0.12m/s

Work is done when:______.a. you apply a force to an object and the object moves in any direction. b. you apply a force to an object and it moves in the same direction.c. you apply a force to an object and it moves in the opposite direction. d. You apply a force to an object and it doesn't move.
Answer:
b
Explanation:
The formula for work done (W) is:
W = Force x Distance moved in the direction of force
This means that the object needs to move in the direction of the force, otherwise no work is done in that direction.

One evening, a student tells her sister that the Sun only appears brighter than other stars because the Sun and stars are different distances from Earth. Her sister disagrees, so the student supports her argument by asking her sister to observe the brightness of streetlights throughout their neighborhood. Which observation would support the student’s argument?
Comparing and analyzing the brightness of near and farther streetlight would support the student’s argument.
Which observation would support the student’s argument?The brightness of nearer streetlight is more as compared to the brightness of the farther light because brightness decreases with the increase in distance.
So we can conclude that comparing and analyzing the brightness of near and farther streetlight would support the student’s argument.

The average velocity of the boat given the data from the question is 6.32 Km/h
What is velocity?Velocity is defined as the rate of change of displacement with time. Mathematically, it is expressed as
Velocity = displacement / time
How to determine the resultant displacementDisplacement 1 (d₁) = 3 KmDisplacement 2 (d₂) = 1 KmResultant displacement (D) =?

Answer:
Most light sources can be classified into three main types: continuous, absorption, and emission. A hot, opaque object, like the filament in an incandescent light bulb, emits a continuous spectrum, having light of all wavelengths. A hot, dense gas is another example of an object that emits a continuous spectrum.

A 9 newtwon charge is Felt on a (1x10^-4) C charge from another charge that is 3 meters away. What is the magnitude of that other charge
The magnitude of that other charge will be 9×10⁻⁵ C. The force on the charge is inverse of the distance.
What is Columb's law?The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The magnitude of that other charge is found as;
[tex]\rm F = \frac{Kq_1q_2}{r^2} \\\\ \rm 9 = \frac{9 \times 10^9 \times 1\times 10^{-4}\times q_2}{(3)^2} \\\\ q_2=9\times 10^{-5} \ C[/tex]
Hence, the magnitude of that other charge will be 9×10⁻⁵ C.
