Answer:
I think it is O only nonliving
Q = magnitude of charge at each of the three locations A, B and C = 2 x 10⁻⁶ C
r₁ = distance of charge at origin from charge at B = 50 - 0 = 50 cm = 0.50 m
r₂ = distance of charge at origin from charge at C = 100 - 0 = 100 cm = 1 m
F₁ = magnitude of force by charge at B on charge at origin
F₂ = magnitude of force by charge at C on charge at origin
Magnitude of force by charge at B on charge at origin
inserting the values
F₁ = 0.144 N
Magnitude of force by charge at C on charge at origin
inserting the values
F₂ = 0.036 N
Net force on the charge at the origin is given as
F = F₁ + F₂
F = 0.144 + 0.036
F = 0.18 N
from the diagram , direction of net force is towards left or negative x-direction.
Answer:
Part a)
Weight on surface of other planet = 213.4 N
Part b)
Mass of the Astronaut = 66.0 kg
Part c)
Weight of the Astronaut on Earth = 646.8 N
Explanation:
Part A)
Weight of the Astronaut on the surface of the planet is given as
here we will have
also we have
now we have
Part B)
Mass of the Astronaut will always remains the same
So it will be same at all positions and all planets
So its mass will be
m = 66.0 kg
Part C)
Weight of the Astronaut on Earth is given as
The energy required by the heating process is 0.042 candy bars.
We'll begin by calculating the mass of the water.
- Thickness = 0.5 mm = 0.5 / 1000 = 5×10¯⁴ m
- Area = 1 m²
- Volume = Area × Thickness = 1 × 5×10¯⁴ = 5×10¯⁴ m³
- Density of water = 1000 Kg/m³
- Mass of water =?
Mass = Density × Volume
Mass of water = 1000 × 5×10¯⁴
Mass of water = 0.5 Kg
Next, we shall determine the heat required
- Mass of water (M) = 0.5 Kg
- Initial temperature of water (T₁) = 10 °C
- Final temperature (T₂) = 35 °C
- Change in temperature (ΔT) = T₂ – T₁ = 35 – 10 = 25 °C
- Specific heat capacity of water (C) = 1 Kcal/KgºC
- Heat (Q) =?
Q = MCΔT
Q = 0.5 × 1 × 25
<h3>Q = 12.5 Kcal</h3>
Finally, we shall convert 12.5 Kcal to candy bar.
300 Kcal = 1 candy bar
Therefore,
12.5 Kcal = 12.5/300
12.5 Kcal = 0.042 candy bars
Therefore, the energy required in candy bar is 0.042 candy bars
