2 QUESTIONS!! PLEASE HELP QUICK

Physics
1 answer:
Zolol [24]2 years ago
4 0

Answer:

1. True 2.0

Explanation:

1. When balanced forces are acting on an object, they have a constant velocity, meaning that the velocity remains the same.

2. When an object begins at a starting point and returns back to that same starting point, its displacement would be 0.

I'm pretty confident in these answers, however, you must have studied this more than me, so let me know if you have any questions or concerns at all, I'll be glad to help. :)

With the temperature held constant, the piston of a cylinder containing a gas is pulled out so that the volume increases from 0.
klio [65]

Answer:

P1 = 240 kPa.

Explanation:

Given the following data;

Initial volume = 0.3 m³

Final volume, V2 = 0.9 m³

Final pressure, P2 = 80 kPa

To find the initial pressure, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by the formula;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Substituting into the formula, we have;

P_{1} * 0.3 = 80 * 0.9

0.3P_{1} = 72

P_{1} = \frac {72}{0.3}

P_{1} = 240

Therefore, the initial pressure of the gas is 240 kPa

A net force of 500 N acts on a 100 kg cart. What is the acceleration of the cart if the mass is doubled?
oksian1 [2.3K]

Answer:

2.5 m/s²

Explanation:

You can solve the following equation: F=ma for acceleration.

You'll be left with this:

a=F/m

And then you substitute the force and the doubled mass

a=500N/200kg

a=2.5 m/s²

What is the avarage velocity of a car that travels 30 kilometers due west in 0.5 hours
Fed [463]
Velocity is distance over time v= \frac{d}{t}. If it wants it in km/h you're good to go otherwise if its m/s you need to convert km to m by multiplying 30 by 1000 and t in hours to seconds by multiplying 0.5 by 3600.
