Answer:

Incoming solar radiations

Explanation:

Weather is defined as the condition of atmosphere at any given time. Weather depends upon the temperature, precipitation, air pressure, and cloud covering.

Daily changes in weather comes because of storms and winds while seasonal changes in weather comes because earth revolves around the sun.

As earth is not flat so, when sun shines near the equator region of earth it becomes warm but the polar region at that time is cold because less solar radiations reach that region. Hence, Incoming solar radiations will be the right answer.

An object that floats in water weighs 20 N in air.
Licemer1 [7]

Answer:

a. Weight of Object in Water = 20 N

b. Up thrust = 20 N

c. Weight of Water Displaced = 20 N

Explanation:

a.

The weight of the object remains same in the water as well. Because, the same force of gravity is acting there as well. Hence,

<u>Weight of Object in Water = 20 N</u>

<u></u>

b.

Since, the object floats on the water. Therefore, according to Archimedes' principle the up thrust force acting on the object must be equal to the weight of object:

Up thrust = Weight of object

<u>Up thrust = 20 N</u>

<u></u>

c.

From Archimedes' Principle, we know that the up thrust or the Buoyant force is equal to the weight of the water displaced by the object. therefore:

Weight of Water Displaced = Up thrust

<u>Weight of Water Displaced = 20 N</u>

A small pumpkin is launched from a very versatile catapult at a variety of speeds and angles. The angles are measured relative t
Drupady [299]

Answer:

Explanation:

Maximum height of a projectile

H_{max}=\frac{u^2\sin ^2\theta }{2g}

(1)u=30.7\ m/s

\theta =35.7^{\circ}

H_1=\frac{30.7^2\times \sin ^2(35.7)}{2\times 9.8}

H_1=16.37\ m

(2)u=47.9\ m/s

\theta =33.2^{\circ}

H_2=\frac{47.9^2\times \sin ^2(33.2)}{2\times 9.8}

H_2=35.09\ m

(3)u=21.8\ m/s

\theta =67.7^{\circ}

H_3=\frac{21.8^2\times \sin ^2(67.7)}{2\times 9.8}

H_3=20.75\ m

(4)u=7.7\ m/s

\theta =62.1^{\circ}

H_4=\frac{7.7^2\times \sin ^2(62.1)}{2\times 9.8}

H_4=2.36\ m      

Therefore height reached by pumpkin can be arranged as

H_4
