When touched by a plastic straw, the metal sphere will do what?

1 answer:

5 0

I believe that if you touch a metal sphere with a plastic straw, the straw would not have enough strength to push it. So in that case, the metal sphere will not move and will stay in one place.

Please rate a 5 star

If the action force is the swimmer pushing water in the leftward direction, what is the reaction force?

Sphinxa [80]

According to Newton's Third Law of Motion, to every action, there is an equal and opposite reaction; action and reaction act on different bodies.
Here, the action force is in the leftward direction, so the reaction will be in the opposite direction.
If the action force is the swimmer pushing water in the leftward direction, then the reaction force is in the rightward direction.
And the reaction force will be given by the water on the swimmer.

Answer:

The reaction force is the water pushing the swimmer in the rightward direction.

Hope you could get an idea from here.

Which, if any, of the following statements about electric field lines is/are true? A.The electric field is always perpendicular

jonny [76]

The electric field is always perpendicular to the surface outside of a conductor. TRUE

 If an electron were placed on an electric field line, it would move in a direction perpendicular to the field. FALSE, it would move in an anti-parallel direction because its charge is negative 

Electric field lines originate on positive charge and terminate on negative charge. TRUE ; but they can also go to infinity 

It is possible for two electric field lines to cross each other.
 Usually FALSE; though technically possible at special points where field is zero. 

If an electron and a positron were in the presence of a very strong electric field, they would move away from each other.
 TRUE; one is positive, and one is negative. If the field is strong enough, the action of the field will overcome the mutual attraction between them 

It is not possible for the electric field to ever be zero. FALSE: it IS possible, inside a conductor for instance

If a proton were placed on an electric field line, it would move in a direction anti-parallel to the field.
 FALSE: being positive, it would move in the SAME direction as the fieldic

Three monkeys A, B, and C weighing 20, 26, and 25 lb, respectively, are climbing up and down the rope suspended from D. At the i

Marina86 [1]

Answer: $2235.2lb-ft/s^2$

Explanation:

Given

Mass of monkey A=20lb

Mass of monkey B=26lb

Mass of monkey C=25lb

acceleration of monkey A= $4.2ft/s^2$

acceleration of monkey B=0

acceleration of monkey C= $-5.4ft/s^2$

Force Due to monkey A $\left ( F_A\right )=20\times 4.2 =84lb-ft/s^2\left ( downwards\right )$

Force Due to monkey A $\left ( F_B\right )=26\times 0 =0lb-ft/s^2$

Force Due to monkey A $\left ( F_C\right )=25\times 5.4 =135 lb-ft/s^2\left ( upward\right )$

In addition to it Weights of monkeys will be acting downwards therefore net Downwards force is balanced by tension

T= $\left ( 20+26+25\right )32.2+84-135=2235.2 lb-ft/s^2$

Balanced Forces acting on an object will not change the object's motion. Unbalanced Forces acting on an object will change the c

ale4655 [162]

Answer:

TRUE

Explanation:

The answer is true.

Balance forces acting on a body will not change the motion of the body because the body experiences no net resultant force in one direction. When any body experiences equal forces with opposite directions, the net force or the resultant force experience by the body is zero.

In case of an unbalanced forces, there is a net force acting in one direction and so it causes the body to change in its state of motion in the direction of the net force.

Very unlikely. This is not really a good question for Brainly.
