Answer:
Pascal's principle, also called Pascal's law, in fluid (gas or liquid) mechanics, statement that, in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container
Answer: The Q arrow
Explanation: when the solid is heated it changes into a liquid state first this action represented the Q arrow
Answer:
<em>Amplitude= 8 m</em>
Explanation:
<u>The Amplitude of a Wave</u>
Sinusoidal Function refers to a mathematical curve with a smooth and periodic oscillation. Its name comes from the sine function and is characterized by the amplitude or the maximum displacement or distance moved by a point on a vibrating body measured from its equilibrium position.
To calculate the amplitude from a graph, we measure the maximum point and the minimum point the wave reaches. Then we subtract both values and divide the result by 2.
The shown wave in the figure has a maximum value of 8 m and a minimum value of -8 m. The distance from the maximum to the minimum is 8-(-8)= 16 m, thus the amplitude is 16/2= 8m.
Amplitude= 8 m
Answer:
D. 30m/s
Explanation:
According to the equation of motion
v=u +at
v = Final velocity
u = initial velocity
a = acceleration
t = time taken
Since we don't know the acceleration of the body, we will find its acceleration using newtons first law of motion F = ma
10000 =2000a
a = 5m/s²
initial velocity = 0m/s since the body starts from rest
v is what we are looking for
t = 6seconds
Substituting this datas in the formula
v = 0+ 5(6)
v = 30m/s (D)
