Answer:
The answer is A - Newtons First Law
Explanation:
The law is what we call "Inertia". The law basically states that an object wants to stay where it is. We can see the effect from our cars, albeit with less force. When the car turns right, your body goes left, opposite to the turns direction due to us moving position in the car.
RADIATION
There are three types of heat transfer or heat propagation; conduction, convection and radiation. Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.
Conduction is the heat transfer by contact, immediate contact.
Convection is the transfer of heat through air and water.
<span>Radiation is the transfer of heat regardless of the presence of atoms or particles.<span>

Answer:
The magnitude of the large object's momentum change is 3 kilogram-meters per second.
Explanation:
Under the assumption that no external forces are exerted on both the small object and the big object, whose situation is described by the Principle of Momentum Conservation:
(1)
Where:
,
- Initial and final momemtums of the small object, measured in kilogram-meters per second.
,
- Initial and final momentums of the big object, measured in kilogram-meters per second.
If we know that
,
and
, then the final momentum of the big object is:


The magnitude of the large object's momentum change is:


The magnitude of the large object's momentum change is 3 kilogram-meters per second.

➷ The dependent variable is the variable that is being measured.
In this case, the dependent variable is the amount of force required to stretch the spring.

Answer:

Explanation:
The formula for the single-slit diffraction is

where
y is the distance of the n-minimum from the centre of the diffraction pattern
D is the distance of the screen from the slit
d is the width of the slit
is the wavelength of the light
In this problem,


, with n=2 (this is the distance of the 2nd-order minimum from the central maximum)
Solving the formula for d, we find:
