Answer:
Being a noble gas, hrlium has a small molecular weight and it's chemical stability is high having the tendancy not to create chemical boudaries ( reactions)
Hi, thank you for posting your question here at Brainly.
First, you have to draw the system for better understanding. Pls refer to the attached image.
Since the system is not moving, the summation of forces are zero since they are at equilibrium
Let's base on the 2-kg object first to find the tension (T) of the rope.
Forces in the y-direction = 0 = T - W
0 = T - 2 kg (9.81 m/s2)
T = 19.62 N
Let's base on the 2.41 kg load.
Forces in the y-direction = 0 = Fn - Wy
0 = Fn - (2.41kg)(9.81m/s^2)(cos47)
Fn = 16.12 N
Forces in the x-direction = 0 = Ff + T - Wx
0 = Ff + 19.62 - (2.41kg)(9.81m/s^2)(sin47)
Ff = -2.33 N
The magnitude of the frictional force is 2.33 N.
The answer is b that what I think and feel like it is
Answer:
Current, I = 0.54 A
Resistance, R = 201.6 ohms
Explanation:
Electric power is given in terms of current, I, and voltage, V, as:
P = I*V
I = P/V
The current flowing in the 60 W bulb will be:
I = 60/110 = 0.54 Amps
The resistance can be gotten by using an alternate formula for Power in terms of resistance:
P = V²/R
R = V²/P
R = 110²/60
R = 201.6 ohms
The 60W bulb has a current 0.54A flowing through it and a resistance of 201.6 ohms.
Answer:
Explanation:
We have the relation of continuity equation as for compressible fluid flow:
where:
density of the fluid
A = area of cross-section of the fluid flow
v = velocity of flow
For a compressible fluid, the density varies.
It is also called mass flow rate, having unit as kilogram per second and is proportional to density.
The higher the density more is the mass flow rate of the fluid.
