Explanation:
<em>Work done by torque = magnitude of force * perpendicular distance between the point of action and point(axis) of rotation.</em>
Answer:
a = 120 m/s²
Explanation:
We apply Newton's second law in the x direction:
∑Fₓ = m*a Formula (1)
Known data
Where:
∑Fₓ: Algebraic sum of forces in the x direction
F: Force in Newtons (N)
m: mass (kg)
a: acceleration of the block (m/s²)
F = 1200N
m = 10 kg
Problem development
We replace the known data in formula (1)
1200 = 10*a
a = 1200/10
a = 120 m/s²
Take left to be the negative direction, and right to be positive. That means the forces on the squirrel would be -2N and 3N.
Add all the forces to find the net force on the squirrel. -2N+3N=1N
Because the positive direction is to the right, the net force of 1N is directed to the right.
Answer: LET'S TAKE GRAVITY ON EARTH AS 10 N/KG AND ON MOON AS 0.6 N/KG
a) weight=15kgx10N/kg
= 150N
b) weight=15x0.6=9N
c) mass=is the same so 15kg
d) mass is measured in kg, weight in NEWTONS OR ![KG M/S^{2}](https://tex.z-dn.net/?f=KG%20M%2FS%5E%7B2%7D)
e) when the gravitational force is zero
Explanation:
The speed of a beam of light will appear the same to all observers.
<h3>Speed of light:</h3>
The exact distance that light travels in a vacuum in a second is 299,792,458 meters (983,571,056 feet). This is roughly 186,282 miles per second, or "c," the symbol for light speed in mathematics.
According to Einstein's theory of special relativity, an object (such as a single photon of light) cannot appear to move faster than the speed of light. This physical rule is not broken by Nemiroff's experiment since the laser pointer emits a stream of photons rather than a single photon.
Nothing can move faster than light in a vacuum, according to one of physics' most revered rules. However, in a recent experiment, this speed restriction was broken when a laser pulse traveled at more than 300 times the speed of light.
