Answer:
2,4 second
Explanation:
Change the momentum = F.t
12 = 50 .t
12/50 = t
2,4
Answer:
Explanation:
initial velocity
magnitude of velocity, v = 12 m/s
angle made of velocity with negative x-axis,θ = 60°
We need to calculate x- component of v
velocity is in negative x-direction, v = -12 m/s
now,
Hence, the velocity x-component is equal to -6 m/s.
2. False
Explanation: When a wave's energy increases, the wave length/frequency decreases.
3. Bass Guitar
Explanation: It has the lowest frequency.
4. Frequency
Explanation: The frequency is the number of vibrations per unit of time or the number of waves that passes a point per unit of time.
The answer is A. the same.
Since the container is sealed, their will be no loss of material from the container which means that the mass won’t vary.
