Answer:
2.5m/s²
Explanation:
Given parameters:
Mass of car = 2000kg
Force produced by the car = 5000N
Unknown:
Acceleration of the car = ?
Solution:
According to Newton's second law of motion, Force is a product of mass and acceleration.
Force = mass x acceleration
Now, insert the parameters and find the unknown;
5000 = 2000 x acceleration
Acceleration = 
= 2.5m/s²
Answer:
At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels. ... Since most of the atmosphere's molecules are held close to the earth's surface by the force of gravity, air pressure decreases rapidly at first, then more slowly at higher levels.
Explanation:
The best answer is
A) <span>The atoms in the mineral get rearranged
Over time, and under great pressure, the atoms of a substance can become rearranged, forming a new substance. For example, the intense pressure that carbon underground experiences, perhaps in the form of coal, can rearrange the atoms of the substance to create a diamond. </span>
Answer:
The gravitational acceleration of a planet of mass M and radius R
a = G*M/R^2.
In this case we have:
G = 6.67 x 10^-11 N (m/kg)^2
R = 2.32 x 10^7 m
M = 6.35 x 10^30 kg
Now we can compute:
a = (6.67*6.35/2.32^2)x10^(-11 + 30 - 2*7) m/s^2 = 786,907.32 m/s^2
The acceleration does not depend on the mass of the object.
Given
Three 7 ohm resistor are in series.
The battery is V=10V
To find
The equivalent resistance
Explanation
When the resistance are in series then the resistance are added to find its equivalent.
Thus the equivalent resistance is:
Conclusion
The equivalent resistance is 21 ohm
