Answer:
M=f/a
Explanation:
F=m x a
÷a both sides
F÷a = m
M=f/a
c. rationing
b. a price floor
d. equilibrium
Answer:
c. rationing
Explanation:
Which is an example of a good whose price goes down because of improvements in technology? Why did Communist governments use a command economic system for many years? ... Quantity demanded will exceed quantity supplied, so the price will drop. Excess supply means that producers will make less of the good.
The second image showing an electromagnet is an example of the electromagnetic force in action therefore the correct option is B
It is a type of force that occur between electrically charged particles. The electromagnetic force is the combination of all the electrical and magnetic forces generated from any charged particle,
These electromagnetic forces either be attractive or repulsive.
The force generated from a simple bar magnet is an example of the electromagnative force, hence the correct option is B

Answer:
the answer is A the one that has the green ball as particles
Explanation:
b. 11 kg.
c. 110 kg.
d. 1100 kg.
e. none of the above
A lamb that weighs 110 N has a mass of around 11 kg. Hence, option B is correct except B all options are incorrect.
The mass of a physical body is a measure of its entire makeup. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of a body's gravitational pull on other bodies is also influenced by its mass. The kilogram is the fundamental mass unit of the SI.
In physics and engineering, the weight of an object refers to the gravitational force that pulls on it. Weight is the term used in many widely used textbooks to describe the gravitational force acting on the object. Some people think of weight as a scalar quantity that gauges the gravitational force's strength.
According to the question, the given values are :
Weight, w = 110 N and,
Taking value of g = 10 m/s²
As we know that :
w = m × g
110 = m (10)
m = 11 kg
Hence, the mass of the lamb will be 11 kg.

a. 10N
b. 100N
c. 200N
d. 98N
The smallest value of the force that will make the block not to slide down is 10 N.
We'll begin by calculating the normal reaction. This can be obtained as follow:
N = mg
N = 8 × 10
N = 80 N
Finally, we shall determine the frictional force.
F = μN
F = 0.4 × 80
F = 32 N
Since the frictional force is 32 N, therefore, a force lesser than the frictional force will make the blocknot to slide down.
From the options given above, only option A has a force that is lesserthan the frictional force.
Therefore, the correct answer to the question is Option A. 10 N

The smallest value of the force that will not slide the 8.0 kg block down the wall is 31.36 N.
To determine the smallest value of the force such that the 8.0 kg block will not slide down the wall, we need to consider the static friction between the block and the wall. The formula for static friction is fs = μs * N, where μs is the coefficient of static friction and N is the normal force. In this case, the normal force is equal to the weight of the block, which is mg = 8.0 kg * 9.8 m/s^2 = 78.4 N. Therefore, the smallest value of the force is equal to the maximum static friction force, which can be calculated as fs = 0.4 * 78.4 N = 31.36 N. So the correct answer is 31.36 N.
