The answer to this is Helium :) it's in the farthest right columb and is a noble gas.
please mark as brainliest!
Answer:
Bladder: A temporary storage place for urine
Ureter: Tube that carries urine from the kidneys from the bladder
Nephron: functional unit of the kidney.
Urethra: Exit way for urine out of the body.
Kidney: filters waste from the blood.
I hope this helps! Have an amazing day!
Explanation:
It is given that,
When the front wheels are over the scale, the weight recorded by the scale is 5800 N, F₁ = 5800 N
When the rear wheels are over the scale, the scale reads 6500 N, F₂ = 6500
The distance between the front and rear wheels is measured to be 3.20 m, x₂ = 3.2 m
We need to find the location of center of mass behind the front wheels. Let the center of is located at a distance of x₁. Thus balancing the torques we get :
On solving the above equation we get, x₂ = 1.69 m
So, the center of mass is located at a distance of 1.69 meters behind the front wheels.
Answer:
Length of the stake will be 0.3623 m
Explanation:
We have given energy required to fully drive a stake into ground = 0.30 KJ = 300 J
Average resistive force acting on the floor is equal to F = 828 N
We have to find the length of the stake
We know that work done is given by
W = Fd, here W is work done , F is average force and d is the length of the stake
So 300 = 828×d
d = 0.3623 m
So length of the stake will be 0.3623 m
Before she gets into a tuck position, distribution of mass of her body about axis of rotation increases. As a result, her angular velocity decreases. When a diver gets into a tuck position, distribution of mass of her body about axis of rotation becomes less. As a result, her angular velocity increases. During this whole time, there is only one force acting on her body which is her own weight "mg". The net torque acting on her all the time is zero because "mg" force passes through this axis of rotation which causes no moment. Since there is no torque acting on her body, angular momentum should remain constant ( before tuck and after tuck)
Angular momentum is defined as,
L = Iω
Since net torque is zero,
Li = Lf ........... (Li = initial angular momentum, Lf = final angular momentum)
(Iω)i= (Iω)f
Ii = 2.0 kg · m² , ωi = 5.5 rad/s, ωf = <span>11.5 rad/s.
