Answer:
Explanation:
As the current in the ire is towards right and the charge particle is above the wire, the direction of magnetic field due to the current carrying wire is perpendicularly outwards to the plane of paper. It is calculated by the Maxwell's right hand thumb rule. Now by using the Fleming's left hand rule, the direction of force is upwards.
Answer:
Explanation : if two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.
Answer:
The magnitude of magnetic field is 0.011 T in +z direction.
Explanation:
Given that,
Current, I = 17 A
The magnetic force per unit length, 
We need to find the magnitude and direction of the magnetic field in the region through which the current passes. The magnetic force acting on the conductor is given by :
B is magnetic field
For direction,
The magnetic field is in +z direction. Hence, this is the required solution.
Answer: A. I,II and III
Explanation:
Let's describe the situation in a simplified way.
First remember, in ambient temperature, the candle is in solid form.
As you light the candle, the region of the candle near the flame suffers an increase in energy, caused by the heat of the flame. As you know, when we give enough heat to a solid, it will change of phase, from solid to liquid, and this is why the candle melts. Now, this change of phase is due to the heat of the flame, so when the liquid phase is away from the flame (because the flame went out, or because the liquid wax fell and now is far from the flame) the wax will cool down, and return to the solid phase.
Then we must have:
Presence of heat to go from solid to liquid.
Absence of heat to go from liquid to solid.
And we have a flame, then we must have presence of oxygen.
Then the correct option is:
A. I,II and III
The rocket should be fired for <u>129600 seconds.</u>
Why?
We can calculate for how long should the rocket be fired by using the following equation:
From the statement we know:
- Initial speed equal to zero.
- Force equal to 272N.
- Final speed (for the moment) equal to 62 m/s.
- Mass equal to 72000 Kg.
So, substituting and calculating, we have:
Hence, we have:
Variables: Time
Equations:
Answers: The rocket should be fired for 129600 seconds.
Have a nice day!
