Answer:
gas, metal
Explanation:
The three states of by which hydrogen is found in Jupiter is made up of:
- Gaseous hydrogen
- liquid hydrogen
- liquid metal hydrogen
This is also the same states found in Saturn too.
The pressure inside the largest planet in our solar system is very great.
- Hydrogen and helium makes up the entirety of the planet Jupiter.
- It has been discovered that inside this planet, hydrogen often occurs as gas, liquid and metal
- This is often attributed to the huge amount of pressure in the planet.
Given
Weight of the block A, Wa = 20 lb, weight of block B Wb = 50 lb. Applied
force to block A, P = 6lb, coefficient of static friction µs = 0.4, coefficient
of kinetic friction µk = 0.3. If a force P
is applied to the body, no relative motion will take place until the applied
force is equal to the force of friction Ff, which is acting opposite to the
direction of motion. Magnitude of static force of friction between block A and
block B, Fs = µsN, where N is
reaction force acting on block A. Now, resolve the forces Fx = max. P = (mA +
mB)a,
6 = (20 / 32.2 + 50 / 32.2)a
2.173a = 6
A = 2.76 ft/s^2
To check slipping occurs between block A and block B, consider block A:
P – Ff = mAaA
6 – Ff = 1.71
Ff = 4.29 lb
And also,
N = wA. We know static friction,
Fs = µsN
Fs = 0.4 x 20
Fs = 8lb
Frictional force is less than static friction. Ff < Fs
<span>Therefors, acceleration of block A, aA = 2.76 ft/s^2, acceleration of
block B aB = 2.76 ft/s^2</span>
We are given –
- Mass of boiling ball is, m = 4 kg
- Speed is, v = 3 m/s
- Momentum, P =?
As we know –
↠Momentum = Mass × Speed(Velocity)
↠Momentum = 4 × 3 kgm/s
↠Momentum = 12 kgm/s
- Henceforth,Momentum will be 12 kgm/s.
Answer:
Distance between Venus and Sun is 1.0864x10^11 m
Explanation:
Data
T1 (Total time taken by earth to rotate around sun)=365 days
T2 (Total time taken by venus to rotate around sun)=225 days
R1 (Radius b/w Sun and earth)=1.5x10^11m
R2(Distance between Venus and Sun)=?
Solution
Apply Kepler Law
(R2)^3/(R1)^3=(T1)^2/(T2)^2
(R2)^3/(1.5x10^11)^3=(225^2)/(365^2)
R2=1.0864x10^11m
