The correct answer would be the last one
Answer:
x = 7.14 meters
Explanation:
It is given that,
Current in wire 1, 
Current in wire 2, 
Distance between parallel wires, r = 25 cm
Let at P point the net magnetic field equal to 0. The magnetic field at a point midway between the is given by :
Let the distance is x from wire 1. So,
x = 7.14 meters
So, the magnetic field will be 0 at a distance of 7.14 meters from wire 1. Hence, this is the required solution.
Explanation:
The uneven heating causes temperature differences, which in turn cause air currents (wind) to develop, which then move heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures). The atmosphere thus becomes a giant "heat engine", continuously driven by the sun.
Wind is the result of pressure changes in the atmosphere due to temperature.
Answer:
For number 2 "What do living things need to survive" you could say Food, air, water. I can't think of much more but I believe it's what any basic living thing needs. Also for number 3 all the way on the bottom you can say " A species is classified based on the popularity or kind of living thing, or where it originates from like how there's different types of birds. They all come from the same first species but evolve/change genes differently over time." hope this somewhat helped :)
Answer:
New_momentum = 750 [kg.m/s]
Explanation:
Momentum is defined as
M = mass* velocity
Original momentum
M_old = 100 Kg * 5 m/s = 500 [kg.m/s]
If the car pulls over and picks up two people. The mass of the car is now 150 kg, but the velocity stays the same.
New momentum
M_new = 150 Kg * 5 m/s = 750 [kg.m/s]
