Answer:
The force downward acting o the rocket is F=m*g=0.0782kg*9.8m/s^2=0.76636 N
Explanation:
Answer:
1 both increase
2. highest to lowest A C D B
3 the kinetic energy is higher in the larger vehicle as they have the same speed
Explanation:
A is right because I took the test
Distance traveled by the rocket= 1002 m
Explanation:
initial velocity= Vi=0
final velocity= V=445 m/s
time=4.5 s
Acceleration=a=99 m/s²
using kinematic equation
h= Vi t + 1/2 at²
h= 0(4.5) + 1/2 (99) (4.5)²
h=1002 m
Thus the distance traveled by the rocket= 1002 m
Answer:
1. Light is electromagnetic waves while sound is mechanical.
Light wave is transverse and sound is longitudinal.
Explanation:
2.
<i = <r
3.
when distance between source and obstacle and distance between obstacle and screen is finite then the diffraction is fresnal diffraction
when distance between source and obstacle and distance between obstacle and screen is infinite then the diffraction is Fraunhofer's diffraction
