Consider a person along with a frame of reference in each of the following situations. In which one or more of the following situations is the frame of reference an inertial frame of reference?

(a) The person is oscillating in of reference an inertial frame of reference
(b) The person is oscillating in a simple harmonic motion at the end of a bungee cord.
(c) The person is in a car going around a circular curve at a constant speed.
(d) The person is in a plane that is landing on an aircraft carrier.
(e) The person is in the space shuttle during lift-off.
(f) None of the above.

The correct option is F (None of the above).

Explanation:

A frame of reference is a set of coordinate that can be used to determine position and velocity of objects in that frame. The frame of reference is classified into two namely;

- inertial frame of reference and

- non-profit inertial frame of reference.

Inertia occurs when an object at rest remains at rest or an object in motion remains moving in a straight line unless another force acts upon it. Therefore an inertial frame of reference occurs when an object stays either at rest or at a constant velocity unless another force acts upon it. There is no acceleration in this frame of reference as it obeys Newton's first law.

Therefore,all the options from A to E are incorrect as they are non-profit inertial frame of reference since the person and the frame of reference is subject to an acceleration.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

it's a b and
