<h3>What is a resultant vector?</h3>
A resultant vector is the vector sum of two or more vectors.
The given vectors;
- Height of vector A = HA
- Height of vector B = HB
- Height of vector C = HC
The height of vector B is the resultant of the three given vectors.
When the vectors are drawn from head to tail, the vector B forms the resultant of the two other vectors (A and C).
Thus, the resultant of the vectors is

Answer:
P = mgh/t = 61(9.8)(0.32)/1.8 = 106.275555... ≈ 110 W
Explanation:
Power is the rate of doing work.
The work changes her potential energy.
Answer: 18.81m/s^2
Explanation:
Given the following :
Height of building = 0. 1 km = 100m
Horizontal distance = 85m
Using the equation :
S = 1/2gt^2
And S = 100, g = 9.8m/s^2
100 = 0.5(9.8)(t^2)
100 = 4.9(t^2)
t^2 = (100 / 4.9)
t^2 = 20.408
t = 4.5175214
t = 4.52s
Therefore, initial velocity of ball in horizontal direction;
Using the equation:
S = ut + 0.5at^2
a in horizontal direction = 0
Therefore,
S = ut
85 = u × 4.52
u = (85 / 4.52)
u = 18.805
u = 18.81m/s
Answer:
The measurement of the force it takes to work against gravity is called weight. You can measure weight on a scale. If you try to pick up heavy objects, you might need to be as strong as a super hero to lift them. Lifting overcomes the pull of gravity. Heavier objects need to have a strong force to lift them.
Explanation:
so I think it's D
V=IR can be changed to V/R=I so 10V/2 ohms = 5amps so 5 amps is your answer boss
