<span>According to the lecture, all of the following are defense mechanisms except: Moderate Exercise

A defense mechanism is the actions that people do as an excuse so they don't have to deal with their real problem. Moderate exercise on the other hands is the action that people do to maintain their health.</span>

I WILL GIVE BRAINLIEST....<br>Determine the value of F...

aleksley [76]

F should be 10. If The Whole top is 50cm, then we should subtract 10n and 30n which gives us 10.

Or it could be 15 if both top and bottom are 25. 10+15= 25.

A cart of mass 6.0 kg moves with a speed of 3.0 m/s towards a second stationary cart with a mass of 3.0 kg. The carts move on a

IgorLugansk [536]

Answer:1.5

Explanation:

Given

mass of first cart $m_1=6 kg$

initial Velocity $u_1=3 m/s$

mass of second cart $m_2=3 kg$

$u_2=0 m/s$

In the absence of External Force we can conserve momentum

$m_1u_1+m_2u_2=(m_1+m_2)v$

$v=\frac{m_1u_1+m_2u_2}{m_1+m_2}$

$v=\frac{6\times 3+3\times 0}{6+3}$

$v=2 m/s$

Final kinetic Energy of two masses

$K.E._2=\frac{1}{2}(m_1+m_2)v^2$

$K.E._2=\frac{1}{2}\cdot (3+6)\cdot (2)^2$

$K.E._2=18 J$

Initial Kinetic Energy

$K.E._1=\frac{1}{2}m_1u_1^2+\frac{1}{2}m_2u_2^2$

$K.E._1=\frac{1}{2}6\times 3^2+0$

$K.E._1=27 J$

$ratio =\frac{K.E._1}{K.E._2}=\frac{27}{18}=1.5$

A car jumps off a ramp with a Kinetic energy of 5,000 joules. This same car has a gravitational potential energy of 4,685 joules

Sedaia [141]

Answer:

14,653 J.

Explanation:

We know that,

Total mechanical energy is equal to the sum of all the potential and kinetic energies.

Given,

Kinetic energy when a car jumps off a ramp= 5000 J

Potential energy = 4685 J

Potential energy when the car lands= 4968 J

TME = 5000 + 4685 + 4968

= 14,653 J

Hence, the car's total mechanical engery is equal to 14,653 J.
