A jet transport has a weight of 1.87 x 10⁶ N and is at rest on the runway. The two rear wheels are 16.0 m behind the front wheel

, and the plane's center of gravity is 12.0 m behind the front wheel. Determine the normal force exerted by the ground on (a) the front wheel and on (b) each of the two rear wheels.

Answer:

a)  R(fw)  = 46.75*10⁶ (N)

b)  R(rwi) = 70.125*10⁶ [N]

Explanation: See Attached file (the rectangle stands for a jet)

The diagram shows forces acting on the jet

Let R(fw)    Reaction of front wheels and

R(rw)   Reaction of rear wheels

Now we apply the Stevin relation, for R(fw)  and a jet weight as follows

R(fw)/ 4   =  187*10⁶ / 16

Then :

R(fw)  = ( 1/4) *187*10⁶           ⇒   R(fw)  = 46.75*10⁶ (N)

And e do the same for the reaction on rear wheels

R(rw) / 12  = 187*10⁶ /16   ⇒     R(rw) =(3/4)*187*10⁶

R(rw) = 140,25*10⁶ [N]

The last expression is for the whole reaction, and must be devide by 2

because that force is exerted for two wheels, therefore on each of the two rear wheels the reaction will be:

R(rwi) = 70.125*10⁶ [N]

A 1000-kilogram car traveling due east at 15 meters per second hit from behind and receives a forward impulse of 6000 newton-sec
strojnjashka [21]

The change in momentum of the car is 6000 kg m/s

Explanation:

According to the impulse theorem, the change in momentum of an object is equal to the impulse exerted on the object, therefore:

\Delta p = I

where

\Delta p is the change in momentum

I is the impulse exerted

For the car in this problem, the impulse received is

I = 6000 kg m/s (in the forward direction)

Therefore, the change in momentum of the car is equal to this value:

\Delta p = I = 6000 kg m/s (in the forward direction)

We can also calculate what is the new momentum of the car. In fact, the initial momentum is

p_i = mu = (1000 kg)(15 m/s)=15,000 kg m/s

And  so, the new momentum is

p_f = p_i + \Delta p = 15,000 + 6,000 = 21,000 kg m/s

Which property helps to explain differences in the specific heat capacities of
tatyana61 [14]

Answer:

D. Forces between molecules

Explanation:

Specific heat capacity of water can be defined as the amount of heat a gram of water must lose or absorb in order to change its temperature by a degree Celsius. It is measured in Joules per kilogram per degree Celsius (J/kg°C). Generally, the specific heat capacity of water is 4.182J/kg°C and is the highest among liquids.

Mathematically, the specific heat capacity of a substance is given by the formula;

c = \frac {Q}{mdt}

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

Cohesion is a property of water and it typically refers to the attraction between molecules of water which holds them together.

In Science, the property which helps to explain differences in the specific heat capacities of two substances is the forces between molecules.

This ultimately implies that, the more closely bonded the atoms of a substance are, the higher or greater would be the substance's specific heat capacity. Thus, it varies for the various states of matter i.e solid, liquid and gas.
