Thermometric Properties Used In Various Thermometers.
Answer: 10 m/2^2
F=ma
Explanation:
Force = 1000N
1 N is 1 (kg*m/s^2)
Mass = 100kg
F=ma
a = F/m
a = (1000kg*m/s^20/(100kg)
a = 10 m/s^2
<span>The quick way to visualize this is to compare isometric and perspective drawings of a cube. In the isometric drawing, all the edges of the cube would be parallel in sets of four. In the perspective drawing, the edges would taper towards one or more vanishing points.
The isometric drawing, being easier to construct, perserving all scales and dimensions, is the preferred method for mechanical drawings, and are practical for use in the shop. The perspective drawing, which are trickier to draw properly, and does not preserve scales and dimensions, is the preferred method for architectural drawings, because they illustrate what the eye actually sees.</span>
Temperature is how hot a body is.
It is a form of measure of the kinetic energy of the particles of a body.
(The higher the motion of the particles of the body the higher the kinetic energy, the lower the motion of the particles, the lower the kinetic energy)
Answer:
The train is moving with a speed of 57.6 m/s.
Explanation:
Given that,
Distance of observer from the road, d = 40 m (due south)
Velocity of the train, v = 60 m/s (due east)
So,
t is time
Net displacement is given by :
Differentiating above equation wrt t as :
Put t = 4 s
So, the train is moving with a speed of 57.6 m/s.
