Answer
A thin atmosphere does not supply much oxygen, and the heat from the sun would evaporate it, because mercury is close to the sun.
For every reaction, there is an equal and opposite reaction. This means that with every interaction, theres a pair of opposite forces on the object.
Acceleration of the car is 3.375 m/s² and the force of the car moving forward is 5062.5 N
Explanation:
- Acceleration is the rate of change of velocity.
- It is given by the equation, a = change in velocity/time
Here, velocity changes from 0 to 27 m/s and time = 8
⇒ Acceleration = 27 - 0/8 = 27/8 = 3.375 m/s²
- Force is calculated by the equation, F = Mass × Acceleration
- This is based on Newton's second law of motion.
Here, mass of the car = 1500 kg and a = 3.375 m/s²
⇒ Force = 1500 × 3.375 = 5062.5 N
According to the given passage,
Over exposure to UV rays causes skin damage or even cancer.
(If you need further explanation)
Over exposure to UV rays also causes Sunburn (or erythema); is redness of the skin, which is due to increased blood flow in the skin caused by dilatation of the superficial blood vessels in the dermis. High UV doses may also results in edema, pain, blistering, and peeling of the skin a few days following exposure. Other effects includes Suppression of the Immune System, <span>Damage to the Eyes, etc.</span>
