The functions of angles are used to find unknown lengths or angles that can't be measured, in terms of known quantities. The trig functions of angles are ratios of lengths, so they're bare naked numbers without units.
The answer to this question is force
Answer:
42.417 cm³
Explanation:
The formula to find the volume of a cone is :
V =
× π r² h
Here,
r ⇒ radius ⇒ 3 cm
h ⇒ height ⇒ 4.5 cm
<u>Let us find it now.</u>
V =
× π r² h
V =
× π × 3 × 3 × 4.5
V =
× π × 9 × 4.5
V =
× π × 9 × 4.5
V =
× π × 40.5
V =
× 3.142 × 40.5
V =
× 127.251
V = <u>42.417 cm³</u>
First let's convert the time in seconds:

The current is defined as the quantity of charge flowing through a certain section of a circuit per unit of time:

Using I=10 A, and

, we can find the amount of charge flown through the hair dryer in this time:

The charge of a single electron is

, so the number of electrons flown through the hair dryer is the total charge divided by the charge of a single electron:
Answer: 0.076 m/s
Explanation:
Momentum is conserved:
m v = (m + M) V
(0.111 kg) (55 m/s) = (0.111 kg + 80. kg) V
V = 0.076 m/s
After catching the puck, the goalie slides at 0.076 m/s.
