Idk tbh looooooooooooooooooooool
Answer:
The thyroid gland produces thyroxine (referred to as T4), which is a relatively inactive prohormone. The highly active hormone is triiodothyronine (referred to as T3).
Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).
Answer:
B. The force would be the same in both cases.
Explanation:
According to Newton's 3rd law where impulse was equated to the momentum formula.
F × t = M × V
where,
Force = F
V = velocity
Since, Impulse is force multiplied by time, whereas the time of contact is the same for both, therefore the impulse is the same in magnitude for the two trucks.
Case 1: Hitting the other car
Case 2: Hitting the brick wall
In Case 1, both the cars are identical and have same velocity whereas in the Case 2, the wall is stationary.
The case of hitting the brick wall have the same impact force as hitting the other car, because they have the same change in momentum.
Therefore, The force would be the same in both cases.
The mass of a 4,900 newtons bobsled is 500 kilograms.
<u>Answer:</u>
I think its
<em>10 kg</em>
