Answer:

Explanation:
Given that

re= 46 cm
Vp= 180 m/s
We know that


So

Now by putting the all given values in the questions


So the average electric field is
.
Answer:
6.40 m/s
Explanation:
Here we have to consider the conservation of energy
Potential energy of a object = Kinetic Energy
Mgh = 1/2 M (v)2
V = root 2gh
V = root 2*10*20.5
V = 6.40 m/s
Answer:
The radius of the loop is 
Explanation:
Given that,
Current = 0.2kA = 200 A
Number of turns = 35
Magnetic field = 8.9 nT
We need to calculate the radius of one loop
Using formula of magnetic field


Where, I = current
N = number of turns
B = magnetic field
r = radius
Put the value into the formula



Hence, The radius of the loop is 
Answer:
252J
Explanation:
Given parameters:
Distance = 72m
Force = 3.5N
Unknown:
Work done on the house = ?
Solution:
Work done is the force applied to move a body through a particular distance.
Work done = Force x distance
Now insert the parameters and solve;
Work done = 3.5 x 72 = 252J
Answer:
Buwaya
Explanation:
Constellations are the patterns imagined by joining stars together. Ancient people used to imagine these patterns and further related the appearance of constellations with natural phenomenon. Similarly constellations can also be related with a particular season depending upon the visibility. For example, Orion signifies the start of the winters in Northern hemisphere.
The rainy season in Philippines starts in the month of June the same time when Buwaya (local name given to the box in Pegasus constellation) starts being seen in the sky after a brief period of disappearance from the sky.
