Answer:
graph 1
Explanation:
acceleration is defined as change in velocity/ change in time.
A constant acceleration should have a linear line.
Since velocity is in the numerator of the formula it is the dependent variable which will go on the y axis. thus making time the independent going on the x axis.
This makes sense because velocity should depend on time not the other way around. This therefore making the right answer graph 1
Answer:
Slow
Explanation:
As we know that the time period of simple pendulum is given by
Where, l be the effective length of the pendulum and g be the acceleration due to gravity
As the length of the pendulum increase, then the tie period of the pendulum will also increase.
It means the clock run slow.
Answer:
Ball A
Explanation:
Let the initial speed of the balls be u .
Angle of projection for ball A = 20°
Angle of projection for ball B = 75°
As we know that at highest point, the ball has only horizontal speed which always remains constant throughout the motion because the acceleration in horizontal direction is zero.
Speed of ball A at highest point = u Cos 20° = 0.94 u
Speed of ball B at highest point = u Cos 75° = 0.26 u
So, the ball A has bigger speed than B.
