Answer:
<u>Option-(D):</u>Thermal energy unchanged, temperature decreased.
Explanation:
<u>Thermal energy and Temperature,T:</u>
Thermal energy of the system is remained unchanged while the temperature,T of the objects present inside the system is more associated with the objects fundamental properties which each matter shows or exhibits in nature.
While the thermal energy is the flow or exchange of thermal or heat energy between the different objects in interaction to each other.
Answer:
At 6 minutes, the soil temperature at a 45° angle of insolation is higher than at 0°.
At 15 minutes, the soil temperature at a 90° angle of insolation is higher than at 45°
Explanation:
From the moment it leaves Terry's hand ... all the way up and then all the way down ... until the moment the ball hits the ground, its acceleration is 9.8 m/s^2 downward. That's the acceleration of gravity (on Earth), and gravity is the only force acting on the ball.
By the way ... Terry needs to control his rage and go get a job as a pitcher for Major League Baseball. That 100 m/s of his is more than double the speed that professional pitchers typically deliver !
Answer: The distance covered by a certain object which is travelling at a certain speed is calculated through the equation,
d = (V₀)t + 0.5at²
where d is the distance, V₀ is the initial speed, a is deceleration, and t is the time. Substituting the known values,
85 = (V₀)(t) + (0.5)(-0.43 m/s)(t²)
Because we are not given with the initial velocity, our answer would remain as the equation which is written above.

Parallax of the stars is created by :
B. Different locations of Earth in its orbit
Parallax refer to the position of an object (in this case, a star) that will look different if we view it from different positions
