What is the velocity of an object with a mass of 4 kg and a momentum of 24 kg.m/s
Eva8 [605]

Answer:

6m/s

Explanation:

momentum = mass × change in velocity

∆p =m(v)

24 = 4(v)

V =>24/4 = 6m/s

An object is dropped from 600 m. If it is initially at rest and achieves a top speed of 45 m/s just as it hits the ground, what
Brums [2.3K]

Answer:

1.68m/s^2

Explanation:

using V^2=U^2+2×a×s formula.

If,

(Final Velocity)V=45

(Initial Velocity)U=0 because it starts from rest

(Distance)S=600m

(acceleration)a= ?

now,

using formula,

45^2=0^2+2×a×600

2025= 1200a

a=2025÷1200

a = 1.68m/s^2(The unit of acceleration is m/s^2)

Therefore the acceleration is 1.68m/s^2

Hope it works !!!

If the San Andreas Fault moves 200 cm (2 meters) per big earthquake, and plate movement is xx cm/yr (see question above), how ma
weqwewe [10]

Answer:

Option C

80 years

Explanation:

<em>From Scientific records, the rate of movement of the plate is 0.025 meters</em>

Since the fault moves at the rate of 2 meters per year, to obtain the number of years it will takes to produce an earth quake, we will have to divide the rate of movement of the fault by the rate of movement of the plate.

Number of years for earthquake = \frac{2}{0.025}= 80 years.

Hence, it will take 80 years to produce one big earthquake.

A gas expands at a constant pressure of 3 atm from a volume of 0.02 cubic meters to 0.10 cubic meters. In the process it experie
Nonamiya [84]

a) 2.4\cdot 10^4 J

For a gas transformation occuring at a constant pressure, the work done by the gas is given by

W=p(V_f -V_i)

where

p is the gas pressure

V_f is the final volume of the gas

V_i is the initial volume

For the gas in the problem,

p=3 atm = 3\cdot 1.013\cdot 10^5 Pa = 3.039\cdot 10^5 Pa is the pressure

V_i = 0.02 m^2 is the initial volume

V_f = 0.10 m^3 is the final volume

Substituting,

W=(3.039\cdot 10^5 Pa)(0.10 m^3-0.02m^2)=24312 J = 2.4\cdot 10^4 J

b) 3.24\cdot 10^5 J

The heat absorbed by the gas can be found by using the 1st law of thermodynamics:

\Delta U = Q-W

where

\Delta U is the change in internal energy of the gas

Q is the heat absorbed

W is the work done

Here we have

\Delta U = 3.0\cdot 10^5 J

W=2.4\cdot 10^4 J

So we can solve the equation to find Q:

Q=\Delta U + W = 3.0\cdot 10^5 J +2.4\cdot 10^4 J = 3.24\cdot 10^5 J

And this process is an isobaric process (=at constant pressure).
