Answer:
x component 60.85 m
y component 101.031 m
Explanation:
We have given distance r = 118 km
Angle which makes from ground = 58.9°
(a) X component of distance is given by
(b) Y component of distance is given by
These are the x and y component of position vector
As per energy conservation we know that
Energy enter into the bulb = Light energy + Thermal energy
so now we have
energy enter into the bulb = 100 J
Light energy = 5 J
now from above equation we have
Answer:
Explanation:
Use the velocity formula to solve
In this question, you are given velocity , and you are given a distance,
. Time in this question is what you'll need to find.
Start by rearranging the velocity formula, to isolate for t.
Start by multiplying both sides by t
Then divide both sides by v.
Now that you've isolated for time, sub in your values and calculate.
