Answer:
By putting something like a sheet of glass in the water.
Explanation:
Putting a sheet of glass in the water will make the ripples move slower because the speed of a wave depends on the depth of water.
Answer:
The correct solution is "15 kgm/s". A further explanation is given below.
Explanation:
The given values are:
Mass,
m = 5 kg
Velocity,
v = 3 m/s
By applying the formula of momentum, we get
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
Answer:
25 m
Explanation:
The relationship between Velocity, distance and time is given as
S = v/t........................... Equation 1
Where S = average velocity of the car, d = distance covered by the car, t = time
Making d the subject of the equation,
d = vt.................... Equation 2
Given: v = 6.25 m/s, t = 4.00 s.
Substitute into equation 2,
d = 6.25(4)
d = 25 m.
Hence, the distance traveled by the car = 25 m
Answer:
velocity = 16.67[m/s]
Explanation:
To solve this problem we must use the following expression of speed, where we see the relationship between displacement and time.
velocity = displacement/time [m/s]
displacement = 50 [m]
time = 3 [s]
velocity = 50/3
velocity = 16.67[m/s]
