Almost all telescopes have a circular mirror. The area of a circle is proportional to
where
is the radius of the circle, the constant of proportionality being
Therefore the area of 150 meter telescope would be
times bigger than the area of the smaller (10 meter) telescope.
The answer: Solanum tuberosum
Answer:
Thermogenesis:Your body's muscles, organs, and brain produce heat in a variety of ways
Explanation:
For example, muscles can produce heat by shivering. Hormonal thermogenesis: Your thyroid gland releases hormones to increase your metabolism. This increases the energy your body creates and the amount of heat it produces
Answer:
The value is 
Explanation:
From the question we are told that
The length of the solenoid is 
The magnetic field is 
The current is 
The desired temperature is 
Generally the magnetic field is mathematically represented as
=> 
Here 
is the permeability of free space with value
So
=>
Answer:
Option 5. 1 and 3
Solution:
The only forces acting on the tennis ball after it has left contact with the racquet and the instant before it touches the ground are the force of gravity in the downward direction and the force by the air exerted on the ball.
The ball after it left follows the path of trajectory and as it moves forward in the horizontal direction the force of the air acts on it.
In the whole projectile motion of the ball, the acceleration due to gravity acts on the ball thus the force of gravity acts on the ball in the downward direction before it hits the ground.
