Answer:

The solar radiation is one of the main factors that shapes the climate all over the globe, so the climate differs with the less or more solar radiation it gets. The polar regions are cold, this is due to the fact that the solar radiation in here is very obscure, because the solar radiation falls at a very wide angle the heat is dispersed over larger area, thus the land gets very little warmth. The Equator, on the other hand, gets direct solar radiation, the sun light falls at a 90 degrees angle or close to it, so the radiation is more concentrated on a smaller area, thus the warming is bigger.

Kundan who weighs 200N and bijaya who weighs 500N are playing sea saw.If Bijaya is 1m away from the fulcrum,how far should kunda

Tom [10]

Answer:

Kundan should sit at more that 2.5 meters from the location of the fulcrum on the side opposite to the side where Bijaya sits

Explanation:

The given parameters are;

The weight of Kundan, F₁ = 200 N

The weight of Bijaya, F₂ = 500 N

The distance of Bijaya from the fulcrum, d₂ = 1 m

Therefore, for Kundan to lift Bijaya, Kundan should sit at a location further than the point where both the moment of Bijaya and Kundan about the fulcrum are equal

Moment of a force, M = The magnitude of the force, F × The perpendicular distance to the point at which the force acts, d

At equilibrium, the sum of the clockwise moment = The sum of the anticlockwise moment

Taking the moment of Kundan as being in the anticlockwise direction and the moment of Bijaya as acting in the clockwise direction, we have;

F₁ × d₁ = F₂ × d₂

∴ 200 N × d₁ = 500 N × 1 m

d₁ = 500 N·m/(200 N) = 2.5 m

Therefore, when Kundan sits at the point d₁ = 2.5 m, away from the fulcrum on one side of the sea saw and Bijaya sits at the point 1 m from the fulcrum on the other side of the sea saw, both Kundan and Bijaya will have the same moment

For Kundan to lift Bijaya, therefore, Kundan as to sit at a point further than 2.5 m from the fulcrum on the opposite side of the fulcrum from Bijaya.

A force of 30 N is required to hold a spring that has been stretched from its natural length of 20 cm to a length of 35 cm. How

docker41 [41]

Answer:

0.25 J

Explanation:

Given that

Force on the spring, F = 30 N

Natural length of the spring, l1 = 20 cm = 0.2 m

Final length of the spring, l2 = 35 cm = 0.35 m

Extension of the spring, x = 0.35 - 0.2 = 0.15 m

The other extension is 40 - 35 cm = 5 cm = 0.05 m

Work done = ?

Considering Hooke's Law of Elasticity.

We're told that the spring stretches through 15 cm, and thereafter asked to find the work done in stretching it through 5 cm

The question is solved in the attachment below

On which part of the compound light microscope are specimens placed for viewing?.

RUDIKE [14]

The specimen that will be on display is set up on stage. When working at greater magnifications when careful motions of the specimen slide are needed, a mechanical stage is employed.

<h3>What is a compound light microscope?</h3>

A microscope having several lenses and a separate light source is called a compound light microscope.

Ocular lenses are located in the binocular eyepieces of this type of microscope, while objective lenses are located in a rotating nosepiece that is located closer to the specimen.

Hence, the part of the compound light microscope is specimens placed for viewing is stage.
