Answer:
Negative, because the speed is decreasing.
Asteroid 1 has more mass because the same force exerted caused this asteroid to move less therefore having more mass
Current = power/voltage = 1200w/120v = 10 amperes. Constantly. Whenever the heater is turned on and heating.
Answer:
Explanation:
a )
Force at the surface = FR
Value of g at height h = g( 1 - 2 h / R )
force at height h = F_R ( 1 - 2 h / R)
F_R / 2 = F_R ( 1 - 2 h / R)
= F_R - 2 F_R xh / R
F_R / 2 = 2 F_R x h / R
1 / 2 = 2h / R
4h = R
h = R / 4 . Ans
b )
Value of g at depth d = g( 1 - d / R )
force at depth d = F_R ( 1 - d / R)
F_R / 2 = F_R ( 1 - d / R)
= F_R - F_R xd / R
F_R / 2 = F_R x d / R
1 / 2 = d / R
2d = R
d = R / 2
Question
A car travels 300 km in the first 3 hours of a trip. Then it hits traffic and travels only 60 km during the last hour. What is the average speed of the of the car?
300 + 60 = 360 Km (total travel)
3 + 1 = 4 hours (total time)
360 : 4 = 90
C.) 90 Km/h is your answer
