Answer:
infrared, visible and ultraviolet regions.
Explanation:
Answer:
6.86 meters
Explanation:
Let the compression of the string be represented by x, and the height of projection of the toy rocket be represented by h.
So that;
x = 9 cm = 0.09 m
In its rest position (i.e before the launch), the spring has a stored potential energy which is given as;
PE = K
= x 830 x
= 415 x 0.0081
= 3.3615
The potential energy in the string = 3.36 Joules
Also,
PE = mgh
where: m is the mass, g is the gravitational force and h the height.
m = 50 g = 0.05 kg, g = 9.8 m
Thus,
PE = 0.05 x 9.8 x h
3.3615 = 0.05 x 9.8 x h
3.3615 = 0.49h
⇒ h =
= 6.8602
The height of the toy rocket would be 6.86 meters.
hey,
I'm here to help
just multiply each mouse's velocity components
then,
add them all up to get x,y total
Answer:
New acceleration is 20.0 m/s².
Explanation:
F = m*a
F = 0.35 kg * 10.0m/s²
If Force will be doubled , and mass will be the same
we can write
2F = 2*0.35 kg*10.0 m/s²=0.35kg*20.0m/s²
New acceleration is 20.0 m/s².
