The correct answer to the question is 8.33 minutes.
CALCULATION:
The distance of earth from sun s = 150 million km.
We know one million = 10 lakh =
Also 1 km =
Hence, the distance s =
=
The speed of light c = 300,000 km per second
=
We are asked to calculate the time.
The time of the reaching earth is calculated as -
We know one minute = 60 second.
Hence, 500 seconds =
= [ans]
Answer:
Hey hi,
Explanation:
<em>Parachutes are designed to reduce terminal Velocity, so when a person is near to ground will have less speed and the avg speed of person hitting the ground </em><em>with</em><em> parachutes will have 17 mph so which makes the person to easily walk off or fell sleep. </em>

Answer:
20.996 m
Explanation:
Given:
Initial velocity,
Final velocity,
Total time taken, s.
∴ Acceleration is given as,
m/s²
Now, using Newton's equation of motion, we find the displacement.
Displacement is given as:
Plug in 0 for , 4.91257 for and 1.74 for . Solve for .
This gives,
Therefore, the train's displacement in the first 4.91257 s of motion is 20.996 m.
Answer:
It is constructed with a high mass and a high raidus.
Explanation:
The rotational inertia I for every object is calculated as:
cMR^2 = I
where c is a constant, M is the mass of the object and R the radius of the object.
So, for a flywheel, the rotational inertia is calculated as:
I =
Then, for constructed a flywheel with the maximun rotational inertia we have to set the maximum mass and the maximun radius.
Answer:
Protein bars
Explanation:
Protein bars contain low-sugar and have high protein content and are therefore good source of nutrient when it is required to take food on-the-go so as to keep the muscle mass the same when it is not possible to take a meal on busy days or before workout
Protein bars can also be taken as part of easy and fast breakfast when travelling so as to maintain a balanced blood sugar level
