Answer:
Explanation:
Acceleration is expressed in the following formula:
Where:
is the final velocity of the projectile
is the initial velocity of the projectile
is the time
Solving:
This is the acceleration of the projectile

Answer:
404K
Explanation:
Data given, Kinetic Energy.K.E=8.37*10^-21J
Note: as the temperature of a is increase, the rate of random movement will increase, hence leading to more collision per unit time. Hence we can say that the relationship between the kinetic energy and the temperature is a direct variation.
This relationship can be expressed as
where K is a constant of value 1.38*10^-23
Hence if we substitute the values, we arrive at
converting to degree we have
Answer:
The average current is 19.567 A
Solution:
As per the question:
Charge, Q =
Time, t =
Now,
We know that current is constituted by the rate of transfer of the charge per unit time. Thus we can write:
I = (1)
Now, the charge that was transferred is 86 % of the original value.
Therefore,
We replace Q by 0.86Q in eqn (1):
I =
Answer:
Here is an image attached with similar questions.
The correct answer is D where acceleration is function of time.
Explanation:
The force acting on the object is constant.
There is no change in the application of forces.
And we know that Force is the product of acceleration and masses.
Newtons second law:
Regarding mass we know that it can neither be created nor destroyed.
So in we have two constant terms, constant divided by constant will give the same result as
There is no change in acceleration with respect to time
.
So the most appropriate graph where time (t) is changing on but acceleration doesn't changes is D.
The graph will be similar to and will be horizontal to the
.
Option D depicts the same.
