<span>The amount of kinetic energy an object has
depends on its mass and speed.</span>
The independent variable is what type of powder is used, the dependent variable is how long itching lasts and the constant is the amount of powder used (50 grams)
Answer:
reflection of water ,sound and water waves etc
Answer:
The number of complete vibration or wave made in
one second is called frequency.
Answer:
a.6.5025 J
b.6.5025 J
Explanation:
We are given that
Mass of pellet,m=0.27 g=
1 kg=1000 g
Spring constant,k=1800 N/m
x=8.5 cm=
1m=100 cm
a.Potential energy stored in the compressed spring is given by
P.E=


b.By using law of conservation of energy
P.E of spring=K.E of the pellet
K.E of the pellet=6.5025 J
