Answer:
a) tires rubbing, b) the weight has a component parallel to the floor
c) he child's back support, d) The tension of the rope and weight
Explanation:
In this exercise, we are asked to indicate the origin of the forces for the centripetal movement parallel to the rope, e) gravitational force
a) When a car turns, the centripetal force has two origins
* The tires rubbing against the road
* If the road has a lean angle, the component of the weight directed towards the center of the circle also contributes to the centripetal force.
b) the child in general has some degree of inclination with respect to the post, for which the weight has a component parallel to the floor that is responsible for the centripetal movement of the system
c) The bench rotates together with the carousel, so the child's back support is the response to the centripetal force
d) The tension of the rope has two components: the component perpendicular to the movement and the component of the weight (parallel to the rope) the difference of these two forces is the centripetal force
e) The gravitational force of the sun on the earth is what creates the centripetal motion
Ideal Mechanical Advantage (IMA) can be found by using the formula:
IMA = ID/OD
ID = Input Distance
OD = Output Distance
In the question, we are given:
ID = 150
OD = 75
Now, solve the expression with what we have.
IMA = 150/75
IMA = 2
Therefore, the IMA is 2.
Best of Luck!
Answer with Explanation:
We are given that
Dipole moment=C-m
Because
Magnitude of electric field,E= N/C
a.We have to find the magnitude of torque on the dipole when
dipole is parallel to the electric field
i.e
We know that
Substitute the values then we get
Because sin 0=0
b.
By using
Nm
c.
Nm
By using
d.Potential energy, U=
Because cos 0degree=1
i can <u>when do u need it by</u> working on it now!!!
Answer:
2
Explanation:
mars has a shorter year because when it revolves around the sun, it takes less time than, saturn who is millions of miles away from mars, longer. Also, mars is closer to the sun than saturn
