Answer:
The current is
Explanation:
From the question we are told that
The radius of the loop is
The earth's magnetic field is
The number of turns is
Generally the magnetic field generated by the current in the loop is mathematically represented as
Now for the earth's magnetic field to be canceled out the magnetic field generated by the loop must be equal to the magnetic field out the earth
=>
Where is the permeability of free space with value
=>
Answer:
a. It always points perpendicular to the contact surface.
Explanation:
"Normal" means perpendicular. Normal forces are always perpendicular to the contact surface.
Answer:
A box of donuts would cost: b = 3.84 + 0.18f
First, we have to find the total cost of the donuts.
12 x 0.32 = 3.84
Next, we need to determine the cost of the box. However, we don't know the surface area, just the cost per foot. We can multiply the number of square feet of the box by $0.18 to find the cost.
So our equation could be: b = 3.84 + 0.18f (where f is the surface area of the box in square feet)Explanation:
Answer:
Vaporization.
Explanation:
When we heat or raise the energy of any sample, it evaporates. Evaporation is known as a form of Vaporization. When some sample evaporates, then they basically take in heat and when the sample condenses, it cools down by giving out the heat into the surrounding, atmosphere and the energy goes into the atmosphere.
An example of evaporation is the rain cycle. Where it's cooler, water on earth's surface evaporates and travels up through the atmosphere. The cool temperature causing the vapor to condense and back into water drops. When the cloud becomes saturated, the droplets fall to the ground in the form of rain.
Answer:
All the different habitats in our world make up biodiversity
Explanation:
Biodiversity is the sum of different species in life. With different species, it's diverse because it's more than one type.
