The four wheels of a car are connected to the car's body by spring assemblies that let the wheels move up and down over bumps an
maksim [4K]

Answer:

The approximate  spring constant is  k =  55533.33 \  N/m

Explanation:

From the question we are told that

   The  mass of the person is  m =  68 \ kg

     The  dip of the car is  x =  1.2 \ cm  =  0.012 \ m

Generally according to hooks law  

        F  =  k * x

here the force F is the weight of the person which is mathematically represented as

         F =  m * g

=>    m * g  =  k * x

=>     k  =  \frac{m * g }{x }

=>    k  =  \frac{68 *  9.8}{ 0.012}

=>   k =  55533.33 \  N/m

The energy released from condensation in thunderstorms can be very large. Calculate the energy (in J) released into the atmosphe
makkiz [27]

Answer:

7.19 * 10^14J

Explanation:

Given that

Density of water Pwater= 1000kg/m3

R=2.1km = 2.1*10^3m

H= 2.3cm. = 2.3*10^-2m

Lv water= 2256 * 10^3J/kg

First, mass of water need to be calculated, using an imaginary cylinder

Density= Mass /Volume

Mass= Density* Volume

Volume of a cylinder= πR2h

Therefore mass= PπR2H

= 1000 * π * (2.1 *10^3)^2 * (2.3 * 10^-2)

= 3.18 *10^8

Heat Released Qv = mLV

= 3.18*10^8 * 2236*10^3

= 7.19 * 10^14J

Answer:

200000J

Explanation:

Here the 1000N÷m is given. It is the torque. Now torque is a type of force created when an object turns.so it is a force.

100kg crate is the mass of the object.

2m is the height.

So the equation to measure gravitational pot. Enrg. Is = mass x force x height

So 1000x100x2 gives us 200000J.
