Answer:
Because they need more energy.
Explanation:
Stars fuse elements in the first place to get energy. In turn, this makes the elements heavier.
Hope this helped.
Answer:
v ’= - 1.76 10⁻⁴ m / s
Explanation:
We can solve this problem using momentum conservation. Defined a system formed by the patient, his blood and the platform in such a way that the forces are internal and the moment is conserved
initial instnate. Before pumping
p₀ = 0
final instant. Right after the heart pumping
p_f = m v + M v'
where m is the mass of blood and M the mass of the patient + the platform
p₀ = p_f
0 = m v + M v’
v ’= -
let's calculate
v ’= - 0.30
v ’= - 1.76 10⁻⁴ m / s
Answer:
63.57 kg
Explanation:
weight = 140 lbs
Let the mass is m.
1 lbs = 4.45 N
The weight of an object is defined as the force with which our earth attracts the body towards its centre.
Weight is the product of mass of the body and the acceleration due to gravity of that planet.
W = m x g
On earth surface g = 9.8 m/s^2
Now convert lbs in newton
So, 140 lbs = 140 x 4.45 = 623 N
So, m x 9.8 = 623
m = 63.57 kg
Thus, the mass is 63.57 kg.
