The ammeter reading (current) will decrease.
V=IR
I = V/R
so I is inversely proportional to R, i.e. increasing R will cause I to decrease
Answer:
100 Watts
Explanation:
<u>These equations are needed to work out the answer:</u>
- power= work done/ time taken
- work done= force* distance
- force= mass* acceleration
force: 10 kg* 2m/s= 20
work done: 20* 10m=200
power: 200/2=100
A. A control group is given the experimental treatment.
Answer:
2.53 cm³
Explanation:
Volume of cylinder = πr²h; where h is the height and r is the radius and
π = 3.14 approx.
Volume = 3.14 * (1.55/2)² * 1.34 = 2.53 cm³
I divided 1.55 by 2 because we were given the diameter and not radius. Diameter = radius / 2
