False.
Unweathered rock that underlies soul is known as bedrock.
Due to the conservation of electric charge, the current is uniform throughout an electrical circuit.
The answer is B.
Answer:
The pitching speed of the ball is 19.7 m/s
Explanation:
- Here, we can use the third equation of motion,

- whereas v represents the final velocity, u represents initial velocity, a is the acceleration due to gravity and s is the displacement or distance an object traveled
- Here, the initial velocity of the the ball is given as zero and the acceleration due to gravity is 9.8 , the distance 's' is given as 20 m
- Using the equation,

- Hence, the pitching speed of the ball is 19.7 m/s
Answer:
the property of liquid are
1 they can flow from one place to another if surface is slanted
2 it cannot be compressed
1.5 m/s is the velocity.
9.3 m is the length of aisle, over which Distance will be covered.
Time is demanded in which the child will move the cart over the aisle with 1.5 m/s.
v=S/t
and,
t=S/v
Put values,
t=9.3/1.5=6.2 s
