Explanation:
Answer:d
Explanation:
It is good to extend your bare hand forward when you are getting ready to catch a fast-moving ball so you can pull your hand back, increasing the time to slow the ball thus decreasing the force.
While catching impulse is being transferred to hands imparting great force, lowering hand would increase the time so that average force decreases and chances to drop the ball also decreases.
Answer:
(c) increase by a factor of four
Explanation:
energy = power x time, and power = resistance x current ^2. 2^2 = 4.
Answer:
Amplitude.
Explanation:
The velocity of a wave is given by :
velocity = total distance covered/total time taken
In the case of a wave the total distance covered is equal to the amplitude of a wave. It is the maximum displacement covered by the wave. So, the velocity of a wave is a function of its amplitude. Hence, the correct option is (D).
Answer:
Explanation:
There are two main ways to de-starch leaves of a plant - the 'Light Exclusion' Method and the 'Carbon Dioxide Deprivation' Method. The 'Light Exclusion' method is a simpler procedure and is used often. Leaves can be destarched by depriving them of light for an extended period of time, usually 24-48 hours.
