Question:<em> </em><em>Find, separately, them mass of the balloon and the basket (incidentally, most of the balloon's mass is air)</em>
Answer:
The mass of the balloon is 2295 kg, and the mass of the basket is 301 kg.
Explanation:
Let us call the mass of the balloon
and the mass of the basket
, then according to newton's second law:
,
where
is the upward acceleration, and
is the net propelling force (counts the gravitational force).
Also, the tension
in the rope is 79.8 N more than the basket's weight; therefore,
![(2). \:T = m_2g+79.8](https://tex.z-dn.net/?f=%282%29.%20%5C%3AT%20%3D%20m_2g%2B79.8)
and this tension must equal
![T -m_2g =m_2a](https://tex.z-dn.net/?f=T%20-m_2g%20%3Dm_2a)
![(3). \:T = m_2g +m_2a](https://tex.z-dn.net/?f=%283%29.%20%5C%3AT%20%3D%20m_2g%20%2Bm_2a)
Combining equations (2) and (3) we get:
![m_2a = 79.8](https://tex.z-dn.net/?f=m_2a%20%3D%2079.8)
since
, we have
![\boxed{m_2 = 301.13kg}](https://tex.z-dn.net/?f=%5Cboxed%7Bm_2%20%3D%20301.13kg%7D)
Putting this into equation (1) and substituting the numerical values of
and
, we get:
![688N = (m_1+301.13kg)(0.265m/s^2)](https://tex.z-dn.net/?f=688N%20%3D%20%28m_1%2B301.13kg%29%280.265m%2Fs%5E2%29)
![\boxed{m_1 = 2295 kg}](https://tex.z-dn.net/?f=%5Cboxed%7Bm_1%20%3D%202295%20kg%7D)
Thus, the mass of the balloon and the basket is 2295 kg and 301 kg respectively.
Their is no document for us to look at , can you add it so i can help you
10.92N
Explanation:
Given parameters:
Mass of truck = 2.964kg
Velocity of truck = 7m/s
Time taken = 1.9s
Unknown:
Average force on the car = ?
Solution:
According to newton's third law of motion "action and reaction are equal and opposite".
The force with which the truck struck the fence is the same as the force the fence acted on the truck with but in another direction.
From newton's second law:
Force = mass x acceleration
We know that acceleration is the change in velocity with time;
acceleration =
Force = mass x
Force =
= 10.92N

Answer:
Option A
Explanation:
At segment T-U, the substance changes from a liquid to a gas and does not change temperature.
The reason is because latent heat of vaporisation allows for the absorption of heat in the change of state and temperature remains constant until it has fully changed state.
