How do you think Earth’s affects what is happening on the surface ?

1 answer:

8 0

Huge masses of rock rise from deep inside Earth, travel along its surface and then sink back down. The process is known as plate tectonics. We rarely see those changes as they happen. Yet plate tectonics affects everyone.

What happens to the volume of an ideal gas as temperature drops

riadik2000 [5.3K]

Based on the ideal gas equation, the pressure (P), volume (V) and temperature (T) corresponding to n moles of an ideal gas are related as:

PV = nRT

where R = gas constant

Under conditions of constant pressure and number of moles:

The volume is directly proportional to the pressure. Therefore, as the temperature drops the volume will also decrease.

V α T

This is also known as the Charles Law.

A bridge that was 5.0 m long has been washed out by the rain several days ago. How fast must a car be going to successfully jump

amid [387]

Answer:

Speed, v = 7.83 m/s

Explanation:

It is given that,

Length of the bridge, l = 5 m

The road on the far side is 2.0 m lower than the road on this side, x = 2 m

The horizontal distance covered by the car is 5 meters and the vertical distance covered by the car is 2 meters.

Initial speed of the car, u = 0

Let t is the time taken by the car . Using the second equation of motion as :

For vertical distance :

$s=ut+\dfrac{1}{2}gt^2$

$t=\sqrt{\dfrac{2\times 2}{9.8}}=0.638\ s$

Let v is the velocity to jump the stream. It is given by :

Horizontal distance, d = 5 m

$v=\dfrac{5\ m}{0.638\ s}$

v = 7.83 m/s

So, the car should travel with a speed of 7.83 m/s. Hence, this is the required solution.

The force diagram represents a girl pulling a sled with a mass of 6.0 kg to the left with a force of 10.0 N at a 30.0 degree ang

Vilka [71]

Normal Force = 54 N
acceleration = 1.2 m/s^2

For Normal Force:
According to the force diagram, we can come up with the equation (all up and down forces):

10 sin 30 + Normal Force - 58.8 = 0
Normal Force = 53.8 N = 54 N

For acceleration:
According to the force diagram, we can come up with the equation (all left and right forces):

10 cos 30 - 1.5 = (6.0) (Acceleration)
Acceleration = 1.19 m/s^2 = 1.2 m/s^2
