The four strokes in order are the intake stroke, the compression stroke, the power stroke, and the exhaust stroke. Fuel is ignited during the power stroke.
Answer:
B
Explanation:
The process is called Geo-Thermal energy because it's an inexhaustible source of energy
Answer:
6.136 mm
Explanation:
given,
frequency emitted by the bat = 5.59 x 10⁴ Hz
speed of sound = 343 m/s
smallest insect bat can hear will be equal to the wavelength of the sound the bat make.



λ = 6.136 mm
so, the smallest size of insect that bat can hear is equal to 6.136 mm
Answer:
numbers
Explanation:
Virtually all unimaginable processes can be described as the movement of certain objects. To analyze and predict the nature of the movements that result from the different kinds of interactions, some important concepts such as momentum, force and energy have been invented. If momentum, force, and energy are known and expressed in a quantitative way (that is, by numbers) it is possible to establish rules by which the resulting movements can be predicted.
Answer:
The required force is 55.38 N.
Explanation:
First we have to find the spring constant K;
k =
=
= 553.846 N/m
As,
F= -K
or, F= - 553.846 × 0.10
or, F= -55.3846 N
Hence,
= - 
∴
= 55.38 N
The required force to stretch it by this amount is 55.38 N.
