The atmosphere is composed of five?

The atmosphere is composed of five major layers. These layers are, in order from the surface of the earth, troposphere, stratosphere, mesosphere, ionosphere, and exosphere.

troposphere - lowest layer that provides majority of our weather. contains four-fifths of air on the earth and extends to a maximum height of 11 miles at the equator and lesser height at the poles.

stratosphere - extends to the height of 30 miles from the equator and it's the location of the ozone layer.

mesosphere - extends to the height of 52 miles from the equator and is where meteors generally burn up

ionosphere - extends to the height of 430 miles from the equator and is already considered as part of the outer space. It is where satellites orbit around the world.

exosphere - extends to the height range of 620 miles to 6,214 miles from the Earth's surface and merges with interplanetary space

A dog, with a mass of 10.0 kg, is standing on a flatboat so that he is 22.5 m from the shore. He walks 7.8 m on the boat toward

marissa [1.9K]

Answer:16.096

Explanation:

Given

mass of dog $\left ( m_d\right )=10kg$

mass of boat $\left ( m_b\right )=46kg$

distance moved by dog relative to ground= $x_d$

distance moved by boat relative to ground= $x_b$

Distance moved by dog relative to boat=7.8m

There no net force on the system therefore centre of mass of system remains at its position

0= $m_d\times x_d+m_b\dot x_b$

0= $10\times x_d+46\dot x_b$

$x_d=-4.6x_b$

i.e. boat will move opposite to the direction of dog

Now

$|x_d|+|x_b|=7.8$

substituting $x_d$ value

$5.6|x_b|=7.8$

$|x_b|=1.392m$

$|x_d|=6.4032m$

now the dog is 22.5-6.403=16.096m from shore

2- A car on a straight highway goes in the positive direction for 8 km and then backs up for 3.6 km. What are the distance and d

IRISSAK [1]

Answer:

11.6km

4.4km in the negative direction

Explanation:

Distance is the total length of path covered and traveled by a body.

So, for this car on a straight line;

Total distance = 8km + 3.6km = 11.6km

Displacement is the distance traveled along a path and the direction it takes.

It is a vector quantity with magnitude and directional attributes.

For this journey;

Displacement = 8km - 3.6km = 4.4km in the negative direction.

Why do I need to use the Unit Circle in Physics? And how do I use it?

stiks02 [169]

Answer:

The unit circle helps in making so many calculations and equations easy.

Explanation:

You cannot separate the knowledge of trigonometry to application in equations to physics. The unit circle is known to have a radius of one. This means that the distance from the centre of the circle, regardless of the unit of measurement, to any point of the edge of the circle is 1. Since the unit circle is very helpful in trigonometry, and trigonometry in turn is the projection of triangles and angles that is very crucial in the calculation of momentum, velocity and other factors of physics, the importance of the unit circle cannot be overemphasized in physics.

A spherical ball of lead has a diameter of 7.5 cm . what is the mass of the sphere if lead has a density of 11.34 g/cm3? (the vo

Gwar [14]

The diameter of the sphere is 7.5 cm, therefore its volume is
V = [(4π)/3]*(7.5/2 cm)³ = 220.8932 cm³

The density of the lead ball is 11.34 g/cm³, therefore its mass is
m = (220.8932 cm³)*(11.34 g/cm³) = 2.5049 x 10³ g = 2.5048 kg

Answer: 2.5 kg (nearest tenth)
