Answer:
4N
Explanation:
a = (7-3)/5 = 0.8m/s^2
F = ma = (5)(0.8) = 4 Newtons
Answer:
Amplitude and wavelength
Explanation:
- The amplitude of a wave is the maximum displacement of the wave, measured with respect to the equilibrium position (so, for a water wave it is the maximum height of the wave relative to the equilibrium position)
- The wavelength of a wave is the distance between two consecutive crests (or throughs) of a wave. So, for a water wave, it is the distance between two consecutive waves
Therefore, in the example in the problem we have:
- 2 meters corresponds to the amplitude
- 35 meters corresponds to the wavelength
Answer:
41.41 m
Explanation:
When force F is applied on an object of mass m for time t and velocity v₁ is created
F X t = mv₁
F = 95 N , t = .53 s, m = 655 kg
95 x .53 = 655 x v₁
v₁ = .0768 m/s
Applying conservation of momentum on man and satellite
m₁ v₁ = m₂v₂
655 x .0768 = 82 xv₂
v₂ = .6134 m/s
their relative velocity
= .6134 + .0768
= .6902 ( they are in opposite direction )
After 60 second distance between them
= 60 x .6902 m
= 41.41 m

<span>You can see lightning before you can hear the thunder. Which is the best explanation for this?
The best explanation for this statement is the transmission of light in air is faster than the transmission of sound in the air. Light is faster than sound, thus you can see the thunder then you can hear the sound.
Hope I helped :D</span>
Answer:
The answer to your question is: C. -9.81 m/s²
Explanation:
A. 9.81 m/s² acceleration is considered positive when it goes to the center of the earth, so this option is incorrect.
B. 0 m/s² This option is incorrect because acceleration is 0 for a linear motion without acceleration.
C. -9.81 m/s² If a projectile goes to the sky, then the acceleration will be negative.
D. It is not constant. Acceleration is constant.
