_______________, not velocity, is used to calculate the average acceleration.
Answer:
speed
Explanation:
Change in velocity, not velocity, is used to calculate the average acceleration. Velocity is displacement over time.
Acceleration:
It is defined as the ratio of change in velocity to time. It is given by:
Acceleration= Change in velocity / time
a= u-v / t
where,
u= initial velocity
v= final velocity
t= time
Thus, we can conclude that a change in velocity is used to calculate average acceleration.

Shows a car travelling around a bend in the road. The car is travelling at a constant speed. There is a resultant force acting on the car. This resultant force is called the centripetal force. (i) In which direction, A, B, C or D, does the centripetal force act on the car? Tick ( ) one box. A B C D (1) (ii) State the name of the force that provides the centripetal force.
Answer:
This question is incomplete
Explanation:
This question is incomplete but the missing figure is in the attachment below.
When an object is travelling around a circular path, there is a force that tends to draw that object towards the center of the circular path and keep the object moving in the curved path, that force is called the centripetal force. From this description, it can be deduced that the direction of the centripetal force that acts on the car (in the attachment below) is D.
The name of the force that provides this centripetal force is frictional force. This is the force that prevents the car from slipping off the road; keeping it moving in the curved path.
TNT is an example of a high explosive. True False
The statement "TNT is an example of a high explosive." is true.
What is TNT?TNT, short for trinitrotoluene, is a highly explosive chemical compound that is widely used in military and industrial applications. It is a pale yellow crystalline solid that is highly sensitive to heat, shock, and friction. TNT is made by the nitration of toluene, a colorless liquid hydrocarbon that is derived from petroleum.
TNT is known for its high explosive power, which makes it a popular choice for use in bombs, missiles, and other weapons. When TNT is detonated, it releases a large amount of energy in the form of a shock wave and high-temperature gases. This explosive power is due to the presence of three nitro groups (-NO2) in the TNT molecule, which makes it highly unstable and reactive.
Despite its explosive properties, TNT is relatively stable under normal conditions and can be stored and transported safely. It is also relatively easy to manufacture, which has made it a popular choice for military applications since World War I. Today, TNT is still used in a variety of military and industrial applications, although it has been largely replaced by more powerful explosives in some applications.
Therefore, The correct answer is True. TNT (trinitrotoluene) is a high explosive that is commonly used in military and industrial applications. It is highly sensitive to heat, shock, and friction and can release a large amount of energy when it detonates.

The formula can be used to convert temperatures between degrees Fahrenheit () and degrees Celsius (). How many degrees are in the Celsius equivalent of -22 F
Answer:
-30°C
Explanation:
F-32/180 =C-0/100
or, -22-32/180=C/100
or, -54/180*100=C
or, -0.3*100=C
therefore, C= -30

Sara is riding her bike down the road at 35 km/hr. She starts to peddle faster as she
approaches and rides up a hill. She accelerates at 2.0 km/hr2 for 3.0 minutes before
reaching the top of the hill. How long distance) did it take her to get to the top of the
hill?
Answer:
Distance covered to top of the hill was : 1.755 km
Explanation:
Initial velocity = 35 km/hr
Acceleration = 2.0 km/hr²
Time taken to accelerate = 3 minutes = 3/60 hours = 1/20 hours
Formula for acceleration : a = Δv /t
v-u/t ---where u is initial velocity , v is final velocity and t is time taken for acceleration
v- 35 / 0.05 = 2
v = 35.10 km/h
Formula for distance is product of speed and time
Distance covered = 35.10 * 0.05 = 1.755 km

A force of 900N acts on
a stationary body
for 40sec and the body acquires the velocity of360 m/s calculate mass a body.
Answer:
Explanation:
It is still using F = m*a -- just in a disguised form.
Givens
F = 900 N
vf = 360 m/s
vi = 0
t = 40 second
Formulas
a = (vf - vi)//t
F = m * a
Solution
a = (360 - 0)/ 40
a = 9
F = m * a
900 = m * 9
m = 900/9
m - 100 kg. Doesn't seem high enough.
Answer:
a= V- u/t
a= 360 - 0 /40 = 9 m/sec2
F = MA
900 = M * 9
M = 900/9
M= 100 kg

How do photons help explain the photoelectric effect?
A. Changing light frequencies create opposing electric fields that affect electrons.
B. "Packets" of electromagnetic energy eject electrons.
C. Particles with positive charge attract negative electrons.
D. Single particles of light take the place of electrons that have similar mass and energy.
Answer:
Option B
"Packets" of electromagnetic energy eject electrons.
Explanation:
A photon is a tiny packet of light. Light as we know is a form of electromagnetic energy. Whenever light is incident on a photoelectric surface, the energy of the light wave gets transferred to the electron, causing it to have enough energy to eject electrons from its surface. The electrons, once ejected, are now free to move about, thus, resulting in the flow of electrical current.
This makes option B the correct answer
