An electron is located 1 meter from a +2 Coulomb charge, as shown below. The electrostatic force acting on the electron is directed toward which point?

The least tension will be experienced by T3

The weight of a moving object causes tension, which is the force applied along the length of a string, rope, or cable. The force that maintains an object moving in a circular direction when it is in a vertical circular motion is called tension. Perpendicular to the circle's radius, the tension in the string is pointed in the direction of the circle's centre.

Due to the centripetal force required to maintain the object moving in a circular motion, the tension in the string varies as the object moves in a vertical circle, with the highest tension occurring at the top of the circle and the least tension occurring at the bottom. In the given case, T3 will experience the least tension during vertical circular motion, assuming that the speed of the ball remains constant. This is because T3 is the point on the string that is closest to the circle's centre, and thus is subject to the least amount of tension as the ball moves in a vertical circle.

It is true that on looking vertically down into the water the black line appears to be closer that it really is.

A material's refractive index, which is quantified, indicates how much a light path is bent or refracted when it penetrates that material.

The critical angle for total internal reflection and the amount of light that is reflected when it reaches the contact are both determined by the index of refraction.

Due to the refraction of light rays as they pass through water and into the air, an item seen in the water typically appears to be deeper than it actually is.

Since the angle subtended by the object is greater, it "appears" larger because the light's refraction away from the normal changes the angle at which the light appears at the eye.

Thus, the given scenario is true.

The new velocity of the object after the event is 7.99m/s.

We are given that,

Mass = m = 50kg

Initial velocity = v = 11.2m/s

Energy = E = 1539j

The kinetic energy of object can be calculated as,

K= (1/2)mv²

K = (50×125.44)/2

K = 3136J

Consequently, since both the initial kinetic energy and the total amount of energy transferred are known. The article's resulting energy is easily discernible.

Final energy = initial kinetic energy - the ending energy

Final energy  = 3136-1539= 1597 joules

Therefore, using the equation for kinetic energy derivation, the speed of the object can now be determined.

K.E = 1/2MV²

1597 = 50/2V²

3194 = 50V²

V = 7.99m/s

Therefore , the new velocity of the object after the event would be 7.99m/s.

Explanation:

In the particles of a substance when heat is released and the temperature becomes lower are the particles will move more slowly.

A particle can vibrate due to heating so that the particle can be said to have kinetic energy. Kinetic energy itself is affected by the mass and speed of objects. The smaller the mass of an object, the greater its kinetic energy. The faster the particles vibrate, the greater their kinetic energy.

When a particle is heated, its temperature will rise and the particle will move fast because it gains kinetic energy. Meanwhile, when a particle loses heat, the temperature of the particle will decrease, this causes a decrease in the kinetic energy of the particle due to heat loss so that the particle moves slower.

The frictional force when an object moves on the horizontal surface is given as,

Ff = μ N

where, N is the normal force

μ is the coefficient of static or kinematic friction

If no forces other then the weight and the normal are acting upon the y-direction, then the weight and the normal force are equal in magnitude.

N = W = m g

Given that,

Mass of the crate = 26 kg

Frictional force Ff = 70 N

According to the given statement The ships average acceleration is 2790 km/hr².

Rate of change in both speed and direction of motion over time. A point or object going straight forward is accelerated when it accelerates or decelerates. Even though the speed is constant, motion on a circle accelerates because of direction is always shifting

We know that from newton's equation,

v² + u² = 2as

S = ut + 0.5 at²

Where, v = final speed

           u = initial speed

           a = acceleration

           S = distance covered

            t = time taken

Given, u = 0

So the equations becomes:

v² = 2as

S = 0.5 at²

Using these equations we get:

v² = 2a(0.5)at²

v² = a²t²

v = at

v/t = a

Given,  v = 93 km/hr

          t = 2 min = 2/60 hr

Putting these values in above equation we get, a = 2790 km/hr²

The ideal mechanical advantage is 5.

Here, we have value larger radius , R = 20 cm and smaller radius = 4 cm

So, as per the problem, mechanical advantage will be 20/4 = 5.

A wheel and axle must be permanently joined in order to be considered a simple machine, and the wheel must by definition have a bigger radius than the axle. A point on the wheel moves a distance of 2 R whereas a point on the axle moves a distance of 2 r when you turn the wheel through a full revolution, which likewise causes the axle to turn through a full revolution.

The force you apply F R times the distance the point moves equals the effort W required to move a point on the wheel through one full revolution. Work is energy, and since energy must be conserved, a point on the axle must be subjected to a larger force F r because it moves a shorter distance.

The mathematical relationship is:

W = Fr (subscript) ×2πr/θ =F r(subscript) ×2πR/θ

Where ​θ​ is the angle that the wheel is turned.

And therefore:

Fr(r in subscript) / FR(R in subscript) = R/r

The tension in the string can be found by using the equation for centripetal force. which is equal to 150.

This equation states that the centripetal force (Fc) is equal to the mass of the object (m) multiplied by the square of the velocity (v) and divided by the radius (r). Therefore,

Fc = m x v²/r.

In this case, the centripetal force is equal to the tension in the string, so the tension in the string (T) can be found by rearranging the centripetal force equation to

T = m x v²/r.

Substituting in the given values for mass (m) and radius (r) gives

T = 0.304 kg x (2.83 m/s)²/0.44 m

T= 150N

Torque is produced by multiplying the length of a lever arm by the force acting perpendicular to the lever arm. There are two conceivable orientations for the scalar quantity torque: clockwise and anticlockwise.

A torque is created when a force is applied perpendicular to a lever arm. The lever arm or moment arm is the length that extends perpendicularly from the pivot point, or the centre of rotation, to the point at which the force is applied. A torque is always defined with reference to a pivot point.

A torque multiplier multiplies the torque applied to the bolt with each gearing level. For instance, a 5:1 torque multiplier will result in an output.For example, a torque multiplier with a 5:1 ratio will result in an output at the shaft that is five times the torque, but the speed will only be one fifth of the original since no energy can be created.
