Answer:
B
Groundwater in the area will be reduced
Explanation:
because i used my notes and it was there
Power is equal to work divided by time
It depends on the type of question, mechanical condition and given values,
You can use the formula,
Coefficient of static friction = Force of Static friction / Normal force (perpendicular to contacting surfaces)
Hope this helps!
Answer : a quantitative description of kinematics involves using position , time velocity and acceleration to describe the motion.
Explanation : Kinematics are mostly concerned with the geometrically possible motion of an object without consideration of the force and mass involved.
it is used to describe the position of the object , their velocities, time and their acceleration.
we know the equations of motion.
....(I)
....(II)
....(III)
Where, v = velocity
t = time
a = acceleration
s = position , distance
Answer:
at the highest point of the path the acceleration of ball is same as acceleration due to gravity
Explanation:
At the highest point of the path of the ball the speed of the ball becomes zero as the acceleration due to gravity will decelerate the motion of ball due to which the speed of ball will keep on decreasing and finally it comes to rest
So here we will say that at the highest point of the path the speed of the ball comes to zero
now by the force diagram we can say that net force on the ball due to gravity is given by
now the acceleration of ball is given as
so at the highest point of the path the acceleration of ball is same as acceleration due to gravity
