Answer:
option C first gear
Explanation:
we know car is parking in uphill
so is we park park on neutral it will free move that is damage car
so we park car on uphill in first gear and turn wheel away from kerb
and park car on downhill in reverse gear and turn wheel toward kerb
so any gear may be reverse or first
so correct option is C first gear
D is the correct answer.
Heat transfer between two objects happens when energy transfers from the hotter object to the colder object until they reach thermal equilibrium. This can happen through conduction, convection, and radiation.
The transfer of heat between two objects is best explained by the principle that energy is transferred from the hotter object to the colder object, and this occurs until both objects have reached the same temperature. This transfer of heat energy happens primarily through three processes known as conduction, convection, and radiation.
Conduction is the transfer of heat between two objects in direct contact with each other, such as a hot pan warming up food. Convection is the transfer of heat due to the movement of mass, typically within fluids like air or water. Radiation is the transfer of heat through electromagnetic waves, like the heat you feel from the Sun on a sunny day.
When two objects of different temperatures come into contact, like object X with temperature Tx and object Y with temperature Ty, heat flows spontaneously from the hotter object X to the colder object Y. This results in a loss of thermal energy in X and a gain in thermal energy in Y, until both reach a state of thermal equilibrium.

Answer:
He was among the first to propose its existence.
Explanation:
In July of 2012, physicists found it. This last boson was named the Higgs, after the British physicist Peter Higgs, who was among the first to propose its existence.
Answer: The given statement is false.
Explanation:
Kinetic energy is defined as the energy obtained by an object because of its motion.
For example, moving a pulley on the road.
Whereas energy of an object obtained due to its position is known as potential energy.
For example, lifting a book from table to the shelf shows position of the book has changed.
Therefore, we can conclude that the statement kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf, is false.
Answer:
98.13m
Explanation:
Complete question
Daniel is 50.0 meters away from a building. Tip of the building makes an angle of 63.0° with the horizontal. What is the height of the building
CHECK THE ATTACHMENT
From the figure, using trigonometry
Tan(θ ) = opposite/adjacent
Where Angle (θ )= 63°
Opposite= X = height of the building
Adjacent= 50 m
Then substitute the values we have
Tan(63)= X/50
1.9626= X/50
X= 1.9626 × 50
X= 98.13m
Hence, the height of the building is 98.13m
