Answer: 42.1
Explanation:
Mass specific metabolic rate of a dolphin can be defined as the rate at which the dolphin consume energy per unit mass of body weight.
R = E/M
Where R = mass specific metabolic rate
E = Energy consumption = 8000kcalsday
M = mass = 190kg
R = 8000kcalsday/190kg
R = 42.1
Answer:
golf all on grass covered hill in sunlight
Explanation:
someone pouring/spinning top has a lot of motion going on. a roller coaster has force acting on it which increases the motion.
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.
