Magnetic field direction is given by right hand thumb rule.
If we put our thumb in the direction of current then curl of fingers will show the magnetic field direction around the wire.
Now here since current is going into the screen so we will put our thumb into the screen and then the curl of fingers is clockwise around it.
The magnetic field is clockwise.
So this would be the direction of magnetic field
Answer:
The mass will stay the same throughout time
Answer:
49.3 N
Explanation:
Given that Pulling up on a rope, you lift a 4.25 kg bucket of water from a well with an acceleration of 1.80 m/s2 . What is the tension in the rope?
The weight of the bucket of water = mg.
Weight = 4.25 × 9.8
Weight = 41.65 N
The tension and the weight will be opposite in direction.
Total force = ma
T - mg = ma
Make tension T the subject of formula
T = ma + mg
T = m ( a + g )
Substitutes all the parameters into the formula
T = 4.25 ( 1.8 + 9.8 )
T = 4.25 ( 11.6 )
T = 49.3 N
Therefore, the tension in the rope is 49.3 N approximately.
Answer:
C) Turbines
Explanation:
C. because as the water flows, its kinetic energy is used to turn a turbine.
Answer:
Solar radiation may be converted directly into electricity by solar cells (photovoltaic cells). In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
