Answer:
200 K
Explanation:
0 °C = 273 K
-73°C = 273 K - 73 K = 200 K
Answer:
1) Measuring cylinder
2) Top Pan Balance
Explanation:
To find the density of the pebble Nabil should first accurately measure the mass of the pebble using the top pan balance
He should then fill the displacement can till the water reaches the outlet pipe at the to of the cylinder
He should then place the pebble into the cylinder carefully ans allow the water that would start coming out to stop
The volume of water in the displaced cylinder is then measured and the density is found by dividing the mass of the pebble by the volume of water in the measuring cylinder
The actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.
<h3>Wavelength of the light</h3>
The wavelength of the light is determined using the following formulas;
where;
- λ is wavelength
- d is width of the slit
- D is the distance of the screen
- y is distance between the central bright fringe and dark fringe
<h3>Actions that would decrease the width of the central bright</h3>
y = (λD) / (d)
- Decrease in the wavelength of the light
- Increase in the width of the slit
Thus, the actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.

Answer:
<u>Organ</u>
Explanation:
Tissues make up organs which in turn forms the organ system.
Answer:
The average force exerted on the window due to two snowballs is 6 N
Explanation:
Given:
Mass of snowballs Kg
Velocity of snowball
For finding the average force,
Force is equal to the change in momentum,
Here, final velocity is zero so we write,
Where sec
N
Above value of force is due to one ball, but here given in question there are two ball,
N
Therefore, the average force exerted on the window due to two snowballs is 6 N
