Answer:
3924 N
5124 N
4004 N
2884 N
4004 N
Explanation:
m = Mass of elevator = 400 kg
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration
f = Friction force = 80 N
When the elevator is stationary only the acceleration due to gravity will be acting on it
Tension
The tension is 3924 N
The balanced force equation would be
The tension is 5124 N
When velocity is constant acceleration is zero
The tension is 4004 N
The tension would be 2884 N
When velocity is constant acceleration is zero
The tension is 4004 N
1) Speed acquired
The time taken for the motion is
The bus is moving by uniformly accelerated motion, with constant acceleration
, so the speed acquired by the bus after 120 s is
2) The distance traveled is given by the following formula:
where a is the acceleration and t the time. Substituting numbers into the equation, we find
<span>b. the Mesozoic era.
This was the time in which many modern plants, insects, and reptiles began to appear.</span>
Answer:
Principle of Forfeiture
Explanation:
This example illustrates the of Principle of forfeiture. The Principle of Forfeiture guarantees "a right to self defense" to innocents. So this example is a perfect illustration of Prineciple of Forfeiture where an innocent person reports the crime in her self defense considering herself responsible for upholding the Law since she believes that her fellow officers brought this situation upon themselves while prviously they were worthy of her loyality but they lost their credibiltiy through their actions.
