Answer:
less than one light year. We would all be dead if it was more than a light year.
Answer:
A. 20 N
Explanation:
Weight of the book = mass × acceleration due to gravity
= 2 × 10
= 20 N
There's not enough information to find an answer.
I think the idea here is that in descending (416 - 278) = 138 meters,
the glider gives up some gravitational potential energy, which
becomes kinetic energy at the lower altitude. This is all well and
good, but we can't calculate the difference in potential energy
without knowing the mass of the glider.
The energy consumption rate of the oven is
3 kW = 3000 W = 3000 J/s.
The amount of energy supplied is
9 kJ = 9000 J
The time that the oven will run is
(9000 J)/(3000 J/s) = 3 s
Answer: 3 seconds
energy is the correct answer to fill the blank bb :)
