If a car's initial velocity is 24 m/s E, and 3 seconds later the car's
velocity is 12 m/s E, what is the acceleration of the car during those
3 seconds?

Distance = 150 meters

Time = 18 seconds

Answer:

Below

Explanation:

Alkaline earth metals have 2 valence electrons, which means that when they react with other elements, they will lose rather than gain their 2 electrons making them positive ions or cations.

So the correct answer to your question would be....

    C) 2 valence electrons, cations

Answer:

1)When a bullet is fired from the gun with a certain force (action) as a reaction an equal and opposite force is exerted on the gun. 2)when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

Newton's Third law: when object A exerts force on object B, object B simultaneously exert oppositely directed force of equal magnitude on object A.

Answer: acceleration will slow down.

Explanation: Since mass is inversely proportional to acceleration, if you increase the mass at a given force the rate of acceleration slows.

The factory worker need to know is the state of the material at room temperature and atmospheric pressure.

Matter is anything that has mass and occupy space. Everything around is composed of matter. The material can easily be classified by considering the state of matter in which the material is found at room temperature and atmospheric pressure.

Hence, all the factory worker need to know is the state of the material at room temperature and atmospheric pressure. This will tell us whether it is a liquid, solid or gas.

Answer:

Given, kelvin temperature = 300 K

C = K – 273.15

C = 300 – 273.15

C = 26.85

Therefore, 300 Kelvin is equal to a celsius temperature of 26.85 °C

Answer:

This is Newton's second law.

Newton's second law text:

(If a resultant force acts on a body, then an acceleration will give it an acceleration, the magnitude of which is directly proportional to the amount of the net force, and a direction is in the direction of the net force itself)

F=ma

net force = mass x acceleration

Answer:

According to archemdes principle ,if an object displace more water that its volume then it will sink in water

As The hollow sphere of same mass have high volume ,so it will float and solid copper with less volume will sink ....

Energy = (power) x (time)

Energy = (16 watt) x (5 hours)

Energy = 80 watt-hours

or

Energy = 0.08 Kilowatt-hours

or

1 watt = 1 joule/second

5 hours = 18,000 seconds

Energy = (16 joule/sec) x (18,000 sec)

Energy = 288,000 Joules

Explanation:

A unit of electricity is represented in kilowatt-hour (KWh). To calculate units, you need to find the energy consumption. It is easy, just multiply power with time.

(16×5 ) watt-hour=80Wh.

Convert it to kilowatt-hour i.e 0.08 KWh/day.

So 0.08 KWh is the energy consumption for one day.

Answer:

80m/s

Explanation:

The formula for velocity is [ v = s/t ] where s = displacement and t = time.

= 400/5

= 80m/s

Explanation:

first you would need the height of the building in meters then using the formula calculate 32 m/s ÷ the height of the building in meters and you will get your answer

Answer: The acceleration due to gravity increases the velocity of a falling object by 9.8 m/s per

second. Answer B is wrong because velocity increases. Answer C is wrong because the

distance increases every second. Ans. E is wrong because the derivative of distance with

respect to time gives the velocity, not the acceleration.
