15. With an average surface temperature of about 737 K, _______ is the hottest planet.
A. Mars
B. Mercury
C. Earth
D. Venus
Correct answer choice for question 1 is:
D) Nebula.
Explanation:
A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized vapors. Basically, the nebula was a sign for any distributed enormous object, including galaxies behind the Milky Way. Most nebulae are of a large size, some are numbers of light years in diameter. A nebula that is almost visible to the human eye from Earth would appear larger, but no flashing, from close by. The Orion Nebula, the glowing nebula in the sky that controls a region twice the diameter of the full Moon, can be observed with the naked eye but was dropped by early scientists.
Correct answer choice for question 2 is :
D) Venus
Explanation:
Venus is the second planet from the Sun, revolving it every 224.7 Earth days. It has the largest revolution time of any planet in the Solar System and turns in the different direction to most other planets. It does not have any real satellites. It is the second glowing natural object in the night sky after the Moon, leading an obvious magnitude of 4.6 bright quite to throw shadows at night and, unusually, obvious to the naked eye in full daylight.
Answer:
The mass of the object is 0.2 kg
Explanation:
The magnitude of the applied force = 2.0 N
The duration of application of the force = 0.1 second
The increase in velocity given to the body by the force = 1.0 m/s
From the equation of motion under acceleration, we have;
v = u + a·t
Therefore;
a = (v - u)/t
Where;
v = The final velocity
u = The initial velocity
t = The time taken for the change in velocity = 0.1 s
Given that the change in velocity = 1 m/s, we have;
v - u = 1 m/s
∴ a = (v - u)/t = 1 m/s/(0.1 s) = 10 m/s²
The acceleration, a = 10 m/s²
The equation for the applied force, F is F = Mass, m × Acceleration, a
Therefore, when the applied force, F = 2.0 N, and the acceleration, a is a = 10 m/s², we have;
F = Mass, m × Acceleration, a
2.0 N = Mass of the object × 10 m/s²
∴ Mass of the object = 2.0 N/10 m/s² = 0.2 kg
The mass of the object = 0.2 kg.
nuclear energy transformed to electrical energy
chemical energy transformed to electrical energy
radiant energy transformed to mechanical energy
kinetic energy transformed to mechanical energy
Kinetic energy transformed to mechanical energy. The object that is being rotated by the wind gains kinetic energy and the motor, that is connected to the rotating object, gains mechanical energy.
The mechanical energy gained will be transformed into electrical energy once the set up starts to be used for generating electricity.
Answer:
kinetic energy transformed to mechanical energy or D
