Answer:
C. 13.89 meters/second
Explanation:
If the velocity of the train is v=s/t, where s is the distance and t is time, then v=400/5=80m/s. To get the vertical component of the velocity we need to multiply the velocity v with a sin(α): Vv=v*sin(α), where Vv is the vertical component of the velocity and α is the angle with the horizontal. So:
Vv=80*sin(10)=80*0.1736=13.888 m/s.
So the vertical component of the velocity of the train is Vv=13.888 m/s.
Light cells?
If you are referring to solar panels, these convert light energy into electrical energy. They do so by gen<span>erating “DC” (Direct Current) electricity from the light.This electricity is fed into a solar inverter that converts into “AC” (Alternating Current) electricity.<span>The AC electricity is used to power appliances in your home.</span></span>
Explanation:
Given parameters:
Force = 500N
Acceleration =
Unknown:
Weight can be used to this problem = ?
Solution:
Weight is the vertical force on a body;
Weight = mass x acceleration
So from this we can find the mass and then convert to the second wealth.
Answer:
26.64 m
Explanation:
Given the following :
Acceleration at ocean surface = 0.0800 m/s²
Distance covered if initial speed = 0.700 m/s and accelerates to a speed of 2.18m/s
Using the equation :
v² = u² + 2as
Where ;
v = final velocity ; u = initial velocity ; a = acceleration ; s = distance covered
Therefore,
v² = u² + 2as
2.18² = 0.7² + (2 × 0.08 × s)
4.7524 = 0.49 + 0.16s
4.7524 - 0.49 = 0.16s
4.2624 = 0.16s
s = 4.2624 / 0.16
s = 26.64 m
