Answer: A planet orbit is a gravitationally curved path that a celestial body travels around a point in space.
Explanation:
We define planet orbit as the path that a planet (or any other celestial object) has around two focal points (the orbit is an ellipse, the ellipses have two focal points). For example, the moon's orbit is around the Earth is almost circular, while Earth orbit is less circular. This movement is caused by the strong gravitational attraction of the sun, that keeps all the planets fixed in the orbits, this is why this is called a "gravitationally curved path".
the correct option is planet orbit.
Complete Question
A skier leaves a ski jump with a horizontal velocity of 29.4 m/s. The instant before she lands three seconds later, the magnitudes of the horizontal and vertical components of her velocity are: Group of answer choices
A 29.4 m/s; 29.4 m/s.
B 41.6 m/s; 41.6 m/s.
C 29.4 m/s; 41.6 m/s.
D 0; 29.4 m/s.
E 29.4 m/s; 0.
Answer:
Correct option is A
Explanation:
From the question we are told that
The horizontal velocity is
The time taken for the jump is
The velocity along the vertical axis is
substituting values
During the jump the horizontal velocity remains the same as there was a direction change
So the correct option is A
Answer:
The final temperature is 85.86°C.
Explanation:
Given that,
Mass of tea = 200 g
Mass of glass = 150 g
Initial temperature = 25°C
We need to calculate the final temperature
When equilibrium is reached, assuming no heat flows to the surroundings
So,
We know that,
Specific heat of tea = 1.00 cal/gm° C
Specific heat of tea = 0.20 cal/gm° C
Put the value into the formula
Put the value of initial temperature
Hence, The final temperature is 85.86°C.
