Answer:
The force exerted by three charges on the fourth is 
Explanation:
Given:
- The magnitude of three identical charges,
- Length of the edge of the square a=3 cm
- Magnitude of fourth charge ,Q=3 nC
According to coulombs Law the force F between any two charge particles is given by
where r is the radial distance between them.
Since the force acting on the charge particle will be in different directions so according to triangle law of vector addition
Answer:
1.body composition, (2) flexibility, (3) muscular strength, (4) muscular endurance, and (5) cardio respiratory endurance.
Explanation:
because they are floating on top of the liquid mantle.
The water. Take the specific heat of steel, estimate the volume of the nail, you know the volume of the water, which has a specific heat of one. Or be obvious. If you dropped a red hot nail into a liter of cold water, what would happen?
Answer:
Water
Answer:
The magnitude of acceleration of the student is 0.6 m/s²
Explanation:
Given that,
Initial velocity = 2.8 m/s
Final velocity = 4.7 m/s
Time = 3.4 sec
We need to calculate the magnitude of acceleration of the student
Using formula of acceleration
Where, 
= final velocity
= final velocity
t = time
Put the value into the formula
Hence, The magnitude of acceleration of the student is 0.6 m/s²
