The heat remains constant because there’s nothing to cool it down
Given: 280 watts power a day
Unknown: KwH=?in 30 days
Solution: 280 watt-hours per day/1000x30 days
.28 x 30=n
Answer:8.4 kwh
<em>Answer</em>
0.6 teslas
<em>Explanation</em>
When a conductor is inside a magnetic field it experiences a force given by;
Force = ILBsinθ
Where I⇒ current
L ⇒length of the conductor
B ⇒ magnetic field strength
θ ⇒ Angle between the conductor and magnetic field.
F = ILBsinθ
When θ = 90°, Then sin 90 =1 and the formula becomes;
F =ILB
3 = 10 × 0.5 × B
3 = 5B
B = 3/5
= 0.6
magnetic field strength = 0.6 teslas
Answer:
Explanation:
Polarization In this case angle of incidence is not equal to angle of polarization, hence reflected light is partially polarized and transmitted light is also partially polarized. by reflection is explained by Brewster's law,
According to this when unpolarized light incident on glass plate at an angle is called as angle of polarizing the reflected light is plane polarized, and transmitted light is partially polarized. The plane of vibration of polarized light is having plane of vibrations perpendicular to plane of incidence.
Answer:
1. Mass of the Earth is 5.97219 × 10^24 kg
2. Radius of the Earth is 6,371 km
3. Acceleration due to gravity on the surface of the Earth is 9.81 m/s^2
4. Acceleration due to gravity on the surface of the moon is 1.625 m/s^2
Explanation:
The mass and radius of Earth are <u>5.97219 × 10^24 kg</u> ME and <u>6,371 km</u> RE, respectively. The mass and radius of the Moon are approximately 186ME and 27RE, respectively. The acceleration due to gravity on the surface of Earth is <u>9.81 m/s^2</u> . The acceleration due to gravity on the surface of the Moon is most nearly <u>1.625 m/s^2</u>
