Answer
-8.67× 10^6 N/C
Explanation:
The Electric Field is defined as force per unit charge.
E = Q/ 4π£r2
Qv= −6.5 μCm3
Qv = Q/ V= Q/ 4/3 πr3
Hence Q = 4/3 πr3 × Qv
Hence E = 4/3 πr3 × Qv / 4π£r2= Qvr/3£
−6.5 μ × 4/ 3×8.854 ×10^-12
-6.5 × 4 × 10^6/3 = -8.67× 10^6 N/C
Note: £ = 8.854×10^-12m/F
is the permittivity of free space
Qv is the charge per unit volume
V is volume and volume
Use the equation
plug in the variables for the equation. Use 0 for Vf because at the highest point the velocity would be zero. Use -9.8 for acceleration because that is the speed at which gravity pulls down.
your answer would be 2.06122 seconds.
Answer:
1 m/s^2
Explanation:
V = U + at
20 = 15 + a(5)
5a = 5
acceleration = <u>1 m/s^2</u>

Answer:
The question is not improper, But I will try to explain your doubt.
- The pot and part of stove are obviously in contact with each other. It is known <em>as conduction</em>
- The pot on gas stove burner, the air above the stove is heated and because it is gas moves upwards, this is <em>convection</em>. The bottom of the pot and surface of the stove are not 100% flat. Thats why there will be little pockets of air underneath the pot,even if you place it on the stove.
If we heat up the stove as much as then it turns to red, this visible sign is known as<em> radiation.</em>
<em>Therefore all the 3 kinds of heat transfer takes place</em>
