Answer:
torque τ = 24 N-m
torque τ = 11.98 N-m
Explanation:
given data
mass of the ball = 1.5 kg
arm length l = 70 cm = 0.7 m
mass of arm = 4 kg
solution
we get here center of mass that is
center of mass = ..........1
center of mass =
center of mass = 0.44545 m
and
torque will be
torque τ = F × r ×sinθ ...........2
torque τ = (4+1.5)9.8 × 0.4454 × sin90
torque τ = 24 N-m
and now we get magnitude of the torque
magnitude of the torque τ = F × r ×sinθ
magnitude of the torque τ = (4+1.5)9.8 × 0.4454 × sin60
magnitude of the torque τ = 11.98 N-m
Answer:v=0.0485m^3/kg
Explanation:
PV=MRT
PV/M=RT
Pv=RT
P=8.5mpa= 850Kpa
T= 139K
v= RT/P
0.2968*139/850
v=0.0485m3/kg
Error
0.0485-0.002002/0.0485*100%

Answer:
The magnitude and direction of the force applied by Steinberg are approximately 15.192 newtons and 126.704º.
Explanation:
The chew toy is at equilibrium and experimenting three forces from three distinct dogs. The Free Body Diagram depicting the system is attached below. By Newton's Laws we construct the following equations of equilibrium: (<em>Sp</em> is for Spot, <em>F</em> is for Fido and <em>St</em> is for Steinberg) All forces and angles are measured in newtons and sexagesimal degrees, respectively:
(1)
(2)
If we know that , and , then the components of the force done by Steinberg on the chewing toy is:
The magnitud of the force is determined by Pythagorean Theorem:
Since the direction of this force is in the 3rd Quadrant on Cartesian plane, we determine the direction of the force with respect to the eastern semiaxis:
The magnitude and direction of the force applied by Steinberg are approximately 15.192 newtons and 126.704º.
54 is the amount of neutrons there would be
The separation between them is
Concept :
If the force increases, distance between charges must decrease. Force is indirectly proportional to the distance squared.
Given,
Two point charges are brought closer together, increasing the force between them by a factor of 20.
Original force is
F = -------- ( 1 )
Here, are charges and r is the distance between them
New force F' = ----------- (2 )
Divide ( 1 ) and ( 2 )
=
20 =
r' =
Given that force between them are increasing and therefore distance between them decrease by
