Answer:
Because the gravitational attraction of the Sun hold them in motion around it
Explanation:
For an object travelling in a straight path at constant velocity, the net force acting on the object must be zero.
The planets in the Solar System, however, do not experience a zero net force: in fact, the Sun exerts a gravitational attraction on them, whose magnitude is given by
where
G is the gravitational constant
M is the mass of the Sun
m is the mass of the planet
r is the average distance between the Sun and the planet
Due to the presence of this force, the Sun makes the planets 'deviating' from their straight path, forcing them to following an elliptical path around the Sun.
Answer:
0.09 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity.
The S.I unit of acceleration is m/s².
From the question, expression for acceleration is given as
F' = ma
Using Pythagoras Theory,
√(F₁²+F₂²) = ma................... Equation 1
Where F₁ = Force of the First person on the boulder, F₂ = Force of the Second person on the boulder, F' = resultant force acting on the boulder, m = mass of the boulder, a = acceleration of the boulder.
make a the subject of the equation
a = √(F₁²+F₂²) /m................ Equation 2
Given: m = 825 kg, F₁ = 64 N, F₂ = 38 N,
Substitute into equation 2
a = [√(64²+38²)]/825
a = {√(5540)}/825
a = 74.43/825
a = 0.09 m/s²
<h3><u>
Answer:</u></h3>
When it was first made, it was heavier
<h3><u>
Explanation:</u></h3>
So there was originally air in the Ice Cream because they fluff it up like that. When it melts, those are gone.
The solution for the problem is:
Wavelength = Planck’s constant/(mass*velocity)
Planck’s constant= 6.63*10^-34 with units of J-s or kg-m^2/s^2-s
mass = 149g = 0.149 kg
velocity = 95.4.mi/1hr(1609.3m/1mi)(1hr/3600sec) = 42.65m/s
h/mv = 6.63*10^-34 kg-m^2/s^2-s/(42.65m/s*0.149kg)
wavelength = 1.04 *10^-34 m
Answer:0.967meV
Explanation:
-Find the difference in u, so 130.906118-130.90508= 0.001038u
- convert to meV
1 u = 931.494meV
multiply 0.001038 by 931.494
=0.001038 X 931.494
0.967 meV
