Answer:
Explained
Explanation:
Your tutor is completely wrong here. Ampere and volt are both completely different concept. Ampere measure current in circuit, whereas volt measure the potential difference across two points in circuit. It is due to this difference in the potential that leads to flow of current in the circuit. The potential difference is the cause and current is the effect.
Answer:
1) 460.5 N
2) 431.7 N
Explanation:
Draw a free body diagram. There are four forces on the hammer:
Applied force 62.5 N in the +x direction, 30 cm from the ground
Reaction force Rᵧ in the +y direction, at the point of contact
Reaction force Rₓ in the +x direction, at the point of contact
Reaction force F at 31° from the vertical, 4.75 cm to the left of the point of contact
Part One
To find F, sum the moments about the point of contact:
∑τ = Iα
(62.5 N) (30 cm) − (F cos 31°) (4.75 cm) = 0
F = 460.5 N
Part Two
To find Rₓ and Rᵧ, sum the forces in the x and y directions.
∑Fₓ = ma
62.5 N − F sin 31° + Rₓ = 0
Rₓ = 174.7 N
∑Fᵧ = ma
-F cos 31° + Rᵧ = 0
Rᵧ = 394.7 N
The net reaction force at the point of contact is:
R = √(Rₓ² + Rᵧ²)
R = 431.7 N
Answer:
The current increases when the circuit is closed.
Explanation:
As the complete question is not given, the complete question is attached herewith.
From the data the resistors are connected in parallel and the value of Battery EMF is increased thus as the resistance is decreased and the EMF of the battery is increased, thus the current will increase when the switch is closed.
Answer:
t = 0.96 s is the time it takes for the angle to reduce
Explanation:
In the launch of projectiles, the velocity is broken down into its x and y components, the velocity in the x-axis is constant, as there is no acceleration, instead the velocity in the axis and is reduced by the effect of the acceleration of gravity.
We can find Vox for the initial conditions
Voy = Vo sin θ
Voy = 29 sin 36
VoY = 17 m/s
Vox = Vo cos θ
Vox = 29 cos 36
Vox= 23.5 m/s
Vx = Vox
The velocity on the x axis is constant
By trigonometry, we find the firing angle
tan θ = Voy/ Vx
Vy = Vx tan θ
Vy = 23.5 tan 18
Vy = 7.64 m/s
Now that we have the vertical speed we can find the time
Vy = I'm going - g t
t = (Vy -Voy) / g
t = (17 - 7.64) /9.8
t = 0.96 s
Be the time it takes for the angle to reduce
