Answer:
the distance traveled by the sports car is 90 m
Explanation:
Given;
mass of the sports car, m = 500 kg
initial velocity of the sports car, u = 0
final velocity of the sport car, v = 30 m/s
time of motion of the car, t = 6 s
The distance traveled by the sports car is calculated as;
Therefore, the distance traveled by the sports car is 90 m
Answer:
1.5 × 10³⁶ light-years
Explanation:
A certain square region in interstellar space has an area of approximately 2.4 × 10⁷² (light-years)². The area of a square can be calculated using the following expression.
A = l²
where,
A is the area of the square
l is the side of the square
l = √A = √2.4 × 10⁷² (light-years)² = 1.5 × 10³⁶ light-years
Answer:
Epidermis
Explanation:
The epidermis is an important layer forming the skin that is mainly responsible for providing protection from the incoming harmful solar radiations, that are comprised of ultraviolet particles. These UV rays can cause various diseases like skin cancer.
When the solar radiations containing UV radiations (mostly the UV-B type radiation having a wavelength 290-315 nanometer) strikes the cells of human beings, then the protein that is stored within the skin named '7- dehydrocholesterolit (DHC)' is transformed into the vitamin d3 inside the cells.
