Answer:

a) Tension Force

Explanation:

Since the platform suspended by the strings so here weight of the platform is counter-balanced by the force due to strings.

Here all the molecules of string has tendency to connect with each other so that the internal force between the molecules will help them to bound with each other.

Since we know that this force between the molecules are electromagnetic force due to electron sharing between each other

So this force is known as tension force between the molecules.

So here correct answer force the suspension bridges, cables will exert internal tensile force to counter-balance the weight of the platform.

So correct answer will be

Tension force

Hello There!

If i remember correctly, it is tension force.

Hope This Helps You!
Good Luck :)

An electron with speed of 104 m/s enters a ""forbidden"" region where an electric force tries to push it back along its path wit
dangina [55]

Answer:

The distance travelled is 151.22m and it took 0.97s

Explanation:

Well, this is an ARM problem, so we will need the following formulas

x(t)=x_{0} +v_{0} *(t-t_{0} )+0.5*a*(t-t_{0} )^{2}

v(t)=v_{0} +a*(t-t_{0} )

where x_{0} is the initial position (we can assume is zero), v_{0} is the initial speed of 104 m/s, t_{0} is the initial time (we also assume is zero), a is the acceleration of 107 m/s2, v is speed, x is position and t is time.

Now that we have the formulas, we know that when the electron stops it has no speed. Then we calculate how much time it takes to stop.

0=104m/s-107m/s^{2} *t\\t=0.97s

Finally, we calculate the distance travelled in this time

x(0.97s)=104m/s*0.97s+0.5*107m/s^{2}*(0.97s)^{2}=151.22m

The spin of Earth creates the Coriolis effect. This effect causes which current patterns to occur? Choose all that apply
Komok [63]

Answer:

The correct answer is options (1) and (4).

Explanation:

Due to the rotation of the earth Coriolis force is generated. As the earth rotates from the west to the east, it changes the pattern of global wind and ocean water movement.

This force allows the ocean surface water to move in the clockwise direction in the northern hemisphere, and anticlockwise in the southern hemisphere.

Thus, the correct answer is options (1) and (4).
