b. half as strong
c. one-quarter as strong.
Can someone explain this one for me ? :)
Answer:
950.7 N
Explanation:
m1 = 640kg
m2 = 490kg
k = 8.1 kN/m
the spring is compressed by 5.1cm
5.1/100 = 0.051m
F = kx
F = 8100 * 0.051
F = 413.1 N
F is the force of the small crate.
F(small) = ma
431.1 = 490a
a = 431.1/490
a = 0.84 m/s^2
The acceleration for the smaller crate is the same for the large create.
F(large) = ma
= 640 * 0.84
= 537.6N
Total force = F(small) + F(large)
= 413.1 + 537.6
= 950.7N
Answer:
To decrease the current;
1) Use fewer loops or number of turns
2) Use a lower speed of rotation of the coil in the magnetic field
3) Use a weaker magnetic
Explanation:
According to Faraday's Law of induction, which is the basis of the electromagnetism, electromagnetic induction and therefore the basis of the electric generator, can be written as follows;
Where;
ε = The induced voltage
N = The number of turns (loops)
ΔФ = The change in the magnetic flux
Δt = The change in the time (the duration)
Given that voltage is directly related to the current, decreasing the voltage, decreases the current
To decrease the voltage, and therefore, the current we can;
1) Reduce the number of loops in the coil
2) Increase the time change per unit change in flux by slowing down the speed of rotation of the generator
3) Decrease the amount of change in the magnetic field per turn, by using a weaker magnetic
Answer:
Explanation:
We know that,
Where m is mass and v is velocity or speed.
Putting the required values,
divide both side by 144
So the mass of the diver is 70 kg respectively.
Answer: Option (A) is the correct answer.
Explanation:
Vitamins are the organic compounds which are necessary for normal growth and provide nutrition to the body.
Vitamins help in conversion of food into energy and repair cellular damage.
For example, Vitamin C helps in boosting immune system. Vitamin B6 helps in the biochemical reactions occurring in the immune system.
Thus, we can conclude that out of the given options, the statement Vitamins help produce the immune response is most accurate.
The most accurate statement about vitamins is vitamins help produce the immune response. (Option A)
Vitamins play a crucial role in supporting the immune system by promoting the production and functioning of immune cells, aiding in the synthesis of antibodies, and assisting in the maintenance of overall immune health.
They act as cofactors or coenzymes in various biochemical reactions that are essential for the immune response.
While all vitamins are important for overall health, certain vitamins, such as;
are particularly known for their immune-supporting properties.

Answer:
The car's acceleration is: a = 12.44 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 62.2 [m/s]
Vo = initial velocity = 0 (because the car stars from the rest)
a = acceleration [m/s²]
t = time = 5 [s]
62.2 = 0 + a*5
a = 12.44 [m/s²]
