Answer:
3 ohm
Explanation:
Resistance = Voltage/Current
= 6.0/2
= <u>3</u><u> </u><u>o</u><u>h</u><u>m</u>
Answer:
160 watts.
Explanation:
Remark
Power = Work / Time
Work = F * d
Note: Since he is running up stairs he is doing work against gravity.
Givens
- m = 50000 g kg / 1000 grms
- m = 50000 / 1000 = 50 kg
- h = 4 m
- time = 12.5 seconds
- g = 10 m/s^2
Formula
- P = W * d/t
- W = m*g *d / t
Solution
- P = 50kg * 10 m/s^2 * 4 m / 12.5
- <em><u>P = 160 watts. </u></em>

You need to include a picture of the punnet square in order to help you.
Answer:the dart goes 6m deep
Explanation:
1/2 k x1² = mgh1 (1)
1/2 k x2² = mgh2 (2)
Dividing 1 by 2 gives the relation
(x1/x2)²= h1/h2
using given
[x/ (x/2)]²=24/h2
4= 24/h2
h2=6 m
