I think is True! Is the best answer. Because the trumpet it make them sounds like the lips with the musician and it vibrate.
<em>m = 4.3 kg</em>
<em>Hi there ! </em>
<em>use formula</em>
<em>G = m×g => m = G/g</em>
<em>g ≈ 10N/kg</em>
<em>replace G ; g</em>
<em>m = 43N/(10N/kg)</em>
<em>m = 4.3 kg</em>
<em>Good luck !</em>
-981N would be the reaction force of a person be that stands completely still with a mass of 100 kg.
An opposing force to an action force is referred to as a reaction force. The response force that results from surface engagement and adhesion while sliding is known as friction. Usually, the activities of applied forces result in reaction forces and reaction moments.
As,
F = ma
where, F = force
m = mass of object
a = acceleration due to gravity
Plugging in the values we get,
F = 100kg × 9.81m/s
F = 981 N
Since, reaction force acts opposite to action force so the correct answer is -981N.

Answer:
Explanation:
We are asked to find the cyclist's initial velocity. We are given the acceleration, final velocity, and time, so we will use the following kinematic equation.
The cyclist is acceleration at 1.2 meters per second squared. After 10 seconds, the velocity is 16 meters per second.
= 16 m/s - a= 1.2 m/s²
- t= 10 s
Substitute the values into the formula.
Multiply.
We are solving for the initial velocity, so we must isolate the variable 
. Subtract 12 meters per second from both sides of the equation.
The cyclist's initial velocity is <u>4 meters per second.</u>
