Answer:
6m/s
Explanation:
momentum = mass × change in velocity
∆p =m(v)
24 = 4(v)
V =>24/4 = 6m/s
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 !!!
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 =
= 80 years.
Hence, it will take 80 years to produce one big earthquake.
Cell membranes are 50% protein, the proteins are responsible for many biological processes. If the proteins were absent the membrane could not carry out it's intended purpose.
a) 
For a gas transformation occuring at a constant pressure, the work done by the gas is given by

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,
is the pressure
is the initial volume
is the final volume
Substituting,

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

where
is the change in internal energy of the gas
Q is the heat absorbed
W is the work done
Here we have


So we can solve the equation to find Q:

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