Explanation:

Is beacuse of the air within our bodys is exerting the same pressure out wards so tjere is no pressure difference

Answer:

it is because our body itself is not adept enough to resist the air pressure. For every reaction, there be an balanced opposite reaction according to Newton's law. namely, all forces such as air pressure are in proportion therefore we will not perceive air pressure which also means no net force.

Why does it rain a lot?

Vaselesa [24]

Answer:

Clouds are made up of tiny water droplets. ... As more and more droplets join together they become too heavy and fall from the cloud as rain. Warm air can hold more moisture than cool air. When the warmer air is cooled and the moisture condenses, it often rains more heavily.

The dung beetle is known as one of the strongest animals for its size, often forming balls of dung up to 10 times their own mass

salantis [7]

Answer:

The angular speed of rolling ball is 3.23 rad/sec.

Explanation:

Given that,

Radius = 1.95 cm

Speed = 6.30 cm/s

Suppose, we need to find the angular speed of rolling ball

We need to calculate the angular velocity

Using formula of angular velocity

$v = r\omega$

Where, r = radius

$\omega$ = angular velocity

Put the value into the formula

$\omega = \dfrac{v}{r}$

$\omega =\dfrac{6.30}{1.95}$

$\omega=3.23\ rad/sec$

Hence, The angular speed of rolling ball is 3.23 rad/sec.

A machine shop worker reports the mass of an aluminum cube as 176 g. If one side of the cube measures 4 cm, what is the density

Zarrin [17]

-- Since it's a cube, its length, width, and height are all the same 4 cm .

-- Its volume is (length x width x height) = 64 cm³ .

-- Density = (mass) / (volume)

= (176 g) / (64 cm³)

= 2.75 gm/cm³ .

Find the unknown mass of the block 1 needed to balance the bar. Assume that the mass of the bar is negligible. Block 1 is locate

Natasha2012 [34]

Answer:

Incomplete question: The masses of the blocks m₂ = 1.5 kg and m₃ = 2 kg

Explanation:

Given data:

L₁ = length = 0.85 m

L₂ = 0.25 m

L₃ = 0.5 m

m₂ = 1.5 kg
