50*5=250
Momentum will be 250kgm/s^2
Answer: Non metal.
Explanation: Carbon has 4 electrons in it’s valence shell which makes it a metalloid but commonly it is considered as a non metal.
Answer:
V = 42.41cm^3
Explanation:
In order to calculate the volume of the solid, you use the following formula:

where
r: radius of the circular base of the cone = 3 cm
h: height from the circular base to the peak of the cone = 4.5 cm
You replace the values of r and h in the formula for the volume V:

hence, the volume of the solid is 42.41 cm^3
Answer:
216 m
Explanation:
Assuming a straight line:
Δx = vt
Δx = (12 m/s) (18 s)
Δx = 216 m
