Answer:
Drag friction.
Explanation:
If you have a solid object, go through air, it experiences drag because the air molecules push back a tiny bit. This drag is enhanced because in water, the molecules are more resistant than air, that's why if you try to run in knee deep water, you experience much more drag than when you are running with your legs out of the water.
Answer: Option B
Explanation:
When the thermal energy is transferred from a hotter body to the colder body then the transfer of energy takes place until the temperature of both the objects are same.
The energy from the hotter body is transferred to the colder body. Example: The heat transfer from the hotter water takes place into the colder water.
The energy transfer will stop only when the temperature of both the water will be same.
I'm like 98% it's D.
Answer:
The two planetary movements are revolution and rotation.
Explanation:
In the vast solar system, planets traverse while also remaining fixated within the system because of gravity. Each planet is unique and so is its movement, but, at the same time, there are two common types of movements.
Answer: revolution and rotation plz mark as brainliest
Explanation:
Jose wandered for 2 hour with speed at 2 kilometers per hour.
The speed of an item, which is a scalar quantity in everyday usage and kinematics, is the size of the change in that object's position over time or the size of the change in that object's position per unit of time.
The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. The average speed of an item in a period of time is equal to the distance travelled by the object divided by the duration of the period.
Given parameters:
Distancetravelled by Jose = 4 kilometer.
Speed of Jose = 2 kilometers per hour.
Now from definition of speed:
Total time taken = Distance travelled by Jose ÷ Speed of Jose
= 4 kilometer ÷ 2 kilometers per hour.
= 2 hour.
Hence, Jose wandered for 2 hour.
