Weight = (mass) x (acceleration of gravity)
We know the mass. All we need now is the acceleration of gravity. All that other stuff about velocity and time is chaff, launched to confuse our radar.
Answer:
The position on the x axis is 0.32 m.
Explanation:
Given that,
Point charge = 27 nC
Charge = 6 nC
Distance = 1
We need to calculate the distance
Using formula of electric field
Put the value into the formula
Hence, The position on the x axis is 0.32 m.
Explanation:
I don't know what values you have measured, or what <em>Ladybug Revolution</em> is, but I can show you the equations for rotational motion.
Angular displacement is:
Δθ = ω₀ t + ½ αt²
where ω₀ is the initial angular velocity, α is the angular acceleration, and t is time.
Assuming the radius is constant, the arc length is radius times angular displacement.
s = rΔθ
Using the equation for angular displacement, we can see that if two points have the same angular velocity and same angular acceleration, then they also have the same angular displacement.
Answer:
Explanation:
Appears to be the vertexes of a triangle.
AB = √(-6 - (-2))² + (3 - 4)²) = √17
AC = √(-6 - (-8))² + (3 - 3)²) = 2
BC = √(-2 - (-8))² + (4 - 3)²) = √37
Answer:
Explanation:
1.3 g = 1.3 / 2 = .65 moles of hydrogen .
.65 moles = 6.02 x 10²³ x .65 molecules
Translational kinetic energy of one molecule = 1/2 mc² where c is rms speed = 1/2 x 2 x 1.67 x 10⁻²⁷ x ( 1600 )² = 42752 x 10⁻²⁵ J
Translational kinetic energy of .65 moles = 6.02 x 10²³ x .65 x 42752 x 10⁻²⁵ J
= 1673 J approx .
B ) Total thermal energy and total translational kinetic energy are same so
Thermal energy of gas = 1673 J
C ) Net content of thermal energy = 1673 + 500 - 2000 = 173 J
If c be the rms speed
1/2 x 2 x 1.67 x 10⁻²⁷ x .65 x 6.02 x 10²³ c² = 173
6.534 x 10⁻⁴ c² = 173
c² = 264769
c = 514.56 m /s
