Answer:
weight of sealed tube that is filled with iodine gas is 27 gm
Explanation:
As tube is closed therefore mole of gas is enclosed in a tube, thus it will only converted into gas ( Iodine Gas). In the gas form it will going to exert pressure on the wall of a tube. From conservation of mass principle weight of tube remain same, there will be no change in the weight of gas. therefore weight of sealed tube that is filled with iodine gas is 27 gm
Answer:
numbers
Explanation:
Virtually all unimaginable processes can be described as the movement of certain objects. To analyze and predict the nature of the movements that result from the different kinds of interactions, some important concepts such as momentum, force and energy have been invented. If momentum, force, and energy are known and expressed in a quantitative way (that is, by numbers) it is possible to establish rules by which the resulting movements can be predicted.
Answer: 0.83333333333 km/h
Explanation: give brainliest
The current will be divided by 2
Answer:

Explanation:
We are given that
Mass of box=60kg
Net external force applied on the box=90 N
Friction force =30N
We have to find the acceleration of the box.
We know that
Net external force=ma
Substitute the values then we get


Hence, option b is true.
