Answer:
Radians
Explanation:
The angular speed is a measure of the rotation speed of a body. It is defined as the angle rotated by a unit of time. Thus, It refers to the angular displacement per unit time and is designated by the Greek letter . Its unit in the International System is radian per second (rad / s).
Answer:1.55 times
Explanation:
Given
First wavelength
Second wavelength
According wien's diplacement law
where
T=Temperature
Let be the temperatures corresponding to
respectively.
Thus object with is 1.55 times hotter than object with wavelength
Answer:
Explanation:
= Force on one side of the door by first waiter = 257 N
= Force on other side of the door by second waiter
= distance of first force by first waiter from hinge = 0.567 m
= distance of second force by second waiter from hinge = 0.529 m
Since the door does not move. hence the door is in equilibrium
Using equilibrium of torque by force applied by each waiter
