Answer: Time needed: 2.5 s
Distance covered: 31.3 m
Explanation:
I'll start with the distance covered while decelerating. Since you know that the initial speed of the car is 15.0 m/s, and that its final speed must by 10.0 m/s, you can use the known acceleration to determine the distance covered by
on one side of the equation and solve by plugging your values
To get the time needed to reach this speed, i.e. 10.0 m/s, you can use the following equation
Explanation:
Answer: Crescent
Explanation: Image result for In what phase is the moon if it is gaining light and less than half illuminated
Crescent Moons are when it's less than half illuminated, and gibbous when it's more than half. “Waxing” means that the Moon becomes more illuminated night-by-night, and the term “waning” means that it's getting less illuminated each night.
Answer:
38.4 atm
Explanation:
Data obtained from the question include:
V1 (initial volume) = 3200 L
P1 (initial pressure) = 3.00 atm
V2 (final volume) = 250.0 L
P2 (final pressure) = ?
Using Boyle's law equation P1V1 = P2V2, the final pressure can be obtained as follow:
P1V1 = P2V2
3 x 3200 = P2 x 250
Divide both side by 250
P2 = 3 x 3200/250
P2 = 38.4 atm
Therefore, the pressure of the gas if ethylene is supplied by a 250.0 L tank is 38.4 atm
Answer: How hydroelectric plant is better over thermal power plant in creating less pollution?
Explanation:
The thermal power plant utilizes the coal as a fuel. The heat energy so produce after burning coal is used for generating electrical energy. The burning of the coal results in the production of pollutants. The carbon dioxide is also a chief pollutant of coal burning. This can pollute the air.
The hydroelectric plant is better than thermal power plant in the sense no fuel is required for this purpose the energy from water currents are used for generating electrical energy.
So, the citizens should research about hydroelectric plant and try to know how it is efficient in providing routine energy supply and impact it exerts on the environment if used as a source of energy generation.
