Answer:
The value is
Explanation:
Generally the velocity attained by the sled after t = 3.10 s is mathematically evaluated using the kinematic equation as follows
Here u = 0 \ m/s
a = 13.5
So
=>
The is distance it covers at this time is
=>
=>
Now when sled stops its the final velocity is while the initial velocity will be the velocity after its acceleration i.e
So
Here , the negative sign shows that it is deceleration
So
=>
Answer:
the correct statement is
* atoms cannot be created or destroyed
Explanation:
The Datlon atomic model was proposed in 1808 and represents atoms as the smallest indivisible particle of matter, they were the building blocks of matter and are represented by solid spheres.
Based on the previous descriptive, the correct statement is
* atoms cannot be created or destroyed
The rotational effect of a force is called torque.it is the cause of rotation or angular deceleration

Answer:
The ratio of the translational rms speed in the ionosphere to the translational rms near the earth's surface is
Explanation:
The relation between the translational rms speed and the temperature is given by :
So,
When the temperature is three times greater.
The ratio of the translational rms speed in the ionosphere to the translational rms near the earth's surface is :
Hence, this is the required solution.
Answer:
you want to know newtons first law here.
Explanation:
An object that is at rest stays at rest or stays in motion.
