Answer:
Explanation:
Given that,
Current in wire is
I = 10A
And the current makes an angle of 30° with respect to the magnetic field
Then, θ = 30°
And the magnetic field is
B = 0.3 T
Length of the wire is
L = 0.5m
Force on the wire F?
The force on the wire in calculated using
F = iL × B
Where
The magnitude of the cross produce of L and B is
L × B = LB•Sinθ
Then, force becomes
F = iLB•Sinθ
F = 10 × 0.5 × 0.3 × Sin30
F = 0.75 N
The force on the wire is 0.75 Newton
Hello!
Topic: Cinematic
For this we can say:
Initial velocity (u) = 26 m/s
Final velocity (V) = 0 m/s
Time (t) = 3 s
Distance (d) = ¿?
For calculate skidding distance, let's applicate the formula:
Replacing:
The distance is <u>54 meters (m)</u>
Difference between powerful and powerless language<span>
a. Powerless language: people perceive speech using language forms, such as hedges (I think...) tag questions in simple statements (We should head out now for the movies okay?), or disclaimers (or I probably shouldn't say this but...), as ineffective and powerless.
b. Powerful language: Speech free if such usage aforementioned is considered both powerful and effective.</span>
Answer:
4
Explanation:
For gases :
1. The motion of gases molecule is in random manner at the room temperature.
2.The distance between the gas molecule is more and that is why gas can be compress.
3.The attraction force between the gas molecule is negligible or we can say that there is no any force between the gas molecules.that is why gas can be filled in the container.But the motion of the gas molecule does not stop they are still moving inside the container but the space for movement become less.When a gas container heated then the container start to vibrate because the movement of the gas molecule.
So the option 4 is incorrect.
