Answer:440.03 N
Explanation:
Given
horizontal component of acceleration 
vertical component of acceleration 
mass of ball =0.37 kg
Force in horizontal direction
Force in vertical direction 
Therefore net force is


|F|=440.03 N
Explanation:
It is given that,
A nerve signal travels 150 meters per second. It is the speed of the nerve signal. We need to convert the number of kilometers that the nerve signal will travel in the same time.
We know that,
1 kilometer = 1000 meter
1 hour = 3600 seconds


So, the nerve signal will travel at the rate of 540 km/h. Hence, this is the required solution.
Answer:
100kg
Explanation:
Total force =400N+600N=1000N
As we have,
F=m×g
1000N=m×10m/s²
1000N÷10m/s²=m
m=100kg
Answer:
Explanation:
Since the equation for the illumination of an object, i.e. the brightness of the light, is <em>inversely proportional to the square of the distance from the light source</em>, the form of the function is:
Where x is the distance between the object and the light force, k is the constant of proportionality, and f(x) is the brightness.
Then, if you move halfway to the lamp the new distance is x/2 and the new brightness (call if F) is :

Then, you have found that the light is 4 times as bright as it originally was.
Heat can be transferred from one place to another by three methods:
conduction in solids,
convection of fluids (liquids or gases),
radiation through anything that will allow radiation to pass.
