Answer:
Explanation:
We are given that
|v|=11
|w|=23
|v-w|=30
We have to find the value of |v+w|
|a-b|^2=(a+b)\cdot (a+b)=a^2+b^2-2|a||b|cos\theta
Using the formula
Using the formula
Answer:
His first law states that unless it is forced to change its state through external force, every object will remain stationary or move in a straight line at a constant speed. It is usually taken as the definition of inertia.
Explanation:
One of the major forms of energy driving the water cycle is geothermal energy. Heat is responsible for warming up water, which in turn evaporates, and then again returns to Earth's surface in the form of rain.
Answer:
Unit of precision for force is the Newton.
Explanation:
It is the official unit used to describe force in science and mostly abbreviated with the symbol N.
Answer:
Your answer will be A
Explanation:
The Pacific Ocean is very cold, and a cup of hot chocolate is very hot (hence the name). More thermal energy entails a higher temperature, therefore the cup of hot chocolate has more thermal energy and a higher temperature.
