2. Define Young Modulus and Force constant 3. A wire of cross sectional area of 6 x 10-5mand length 50cm stretches by 0.4mm under a load of 3000N. What is the Young's Modulus of the wire?
4. A spiral spring is compressed by 0.03m. Calculate the energy stored in the spring if its force constant is 300Nm-1

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

amplitude

hope this
