The shear force in the block is[tex]F = G*ε = 7.10^3*0.0006855 = 488.75[/tex]kips.

Shear force is a type of mechanical force that can cause an object to deform or break apart when the force is applied parallel to the object's surface.

The shear modulus, G, is a measure of the rigidity of a solid material and is expressed in units of kips per square inch (ksi).

In this case, we are given that G = 7.10^3 ksi.

To calculate the shear force, F,

in the block, we can use the equation F = P(L/2)/(b*t).

Here, P is the applied force (630 kips),

L is the length of the block (15 inches), b is the width of the block (8 inches), and t is the thickness of the block (2 inches).

Plugging in these values, we get[tex]F = 630(15/2)/(8*2) = 488.75[/tex]kips.

Since the block is bonded to a fixed base and a horizontal plate, the shear force in the block will be equal to the shear modulus, G, multiplied by the strain, ε.

The strain is calculated using the formula ε = F/Gt, where F is the shear force calculated above and G is the shear modulus (7.10^3 ksi). Plugging in the values, we get[tex]ε = 488.75/7.10^3*2 = 0.0006855[/tex]

Therefore, the shear force in the block is [tex]F = G*ε = 7.10^3*0.0006855 = 488.75[/tex]kips.

Complete Question:

The location that will have the greatest electric field strength is the surface of the sphere, which is a distance of r away from the center.

This is because the electric field strength is inversely proportional to the square of the distance from the source, so the closer you get to the source, the stronger the electric field will be.

An electric field is an area of influence created by an electric charge, in which electric force is exerted on other charged objects. This electric force is described mathematically by the electric field vector, which specifies the direction and magnitude of the force. Electric fields can be created by stationary charges, or by time-varying magnetic fields. Electric fields can be used to control the motion of charged objects, and are also responsible for many of the phenomena associated with electricity, such as electric potential, capacitance, and electric current.

If the 2 point charges exert a 2.50 N force on each other , and if distance between them is increased by a factor of 4 , then the Force is  0.15625 N.

The Force between two point charges is calculated by Coulomb's law ; that is represented as ⇒ F = k×(q₁×q₂)/r²  ;

where F is = force, k is = Coulomb constant (8.99 × 10⁹ N×m²/C²),

q₁ and q₂ are the magnitudes of the two charges, and r is = distance between them.

If the distance between the charges is increased by a factor of 4, then r will become 4 times larger.

Taking into account the Boyle's law, the original pressure of a gas was 2.5 atmospheres and the original volume was 578 mL.

Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. This is because when the volume decreases, the distance that the particles have to travel is less and therefore more shocks occur in each unit of time, that is, the pressure increases.

Mathematically, if the amount of gas and the temperature remain constant, the product of the pressure and the volume always has the same value:

P×V= k

where:

Being an initial state 1 and a final state 2, it is fulfilled:

P₁×V₁= P₂×V₂

In this case, you know:

Replacing in Boyle's law:

The load indicated by the spring scale is equal to the mass times the acceleration, so the load indicated by the spring scale is 1 kg x 1 m/s2 = 1 kg.

Acceleration is the rate of change of velocity of an object. It is the rate at which something speeds up or slows down, and is usually denoted by the variable 'a'. Acceleration can be positive, negative, or zero. Positive acceleration indicates an increase in velocity while negative acceleration indicates a decrease in velocity. Acceleration can be caused by a variety of external forces, such as gravity, friction, or thrust. It is also related to momentum, as an object with a greater mass will require more force to accelerate. In general, acceleration is measured in meters per second squared (m/s2).

The mass needed to balance the lever scale is equal to the load on the spring scale divided by the acceleration, so the mass needed to balance the lever scale is 1 kg/1 m/s2 = 1 kg.

The ball reaches a height of 1.38 m after the third bounce, if it is initially released 4 m from the floor.

What is height?

Height is a measurement of vertical distance or elevation. It is usually defined as the distance from a reference point, such as the ground or sea level, to a point of interest, such as the top of a building, a mountain, or an object. Height can be measured in various units, including meters, feet, and inches.

To find the height of the ball after the third bounce, we can calculate the height of the ball after each bounce and multiply by a factor that takes into account the loss of energy due to heating.

After the first bounce, the ball will lose 31% of its energy, so it will have only 69% of its initial energy. We can calculate the height of the ball after the first bounce by assuming that the ball's potential energy is equal to its initial height multiplied by its weight and subtracting the energy loss due to heating:

PE = mgh

h = PE / (mg)

h = (0.69 * 4 m * 9.8 m/s^2) / (0.06 kg * 9.8 m/s^2) = 2.86 m

After the second bounce, the ball will lose another 31% of its energy, so it will have only 69% of its energy after the first bounce. We can calculate the height of the ball after the second bounce using the same process:

h = (0.69 * 2.86 m * 9.8 m/s^2) / (0.06 kg * 9.8 m/s^2) = 2.01 m

After the third bounce, the ball will lose another 31% of its energy, so it will have only 69% of its energy after the second bounce. We can calculate the height of the ball after the third bounce using the same process:

h = (0.69 * 2.01 m * 9.8 m/s^2) / (0.06 kg * 9.8 m/s^2) = 1.38 m

The parachute takes longer to fall because of greater air resistance describes the time it takes for the parachute to fall.

How does air resistance slow the fall rate of a parachute?

The drag force resists the downward movement of gravity, pushing the parachute back up. As the parachute falls, the drag increases until it just balances out the pull of gravity. At that point, the parachute stops speeding up and begins to fall at a steady speed.

Why does a parachute increase air resistance?

An open parachute increases the cross-sectional area of the falling skydiver and thus increases the amount of air resistance that he encounters (as observed in the animation below). Once the parachute is opened, the air resistance overwhelms the downward force of gravity.

How does air resistance affect fall time?

With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down.

Her average velocity is 2.65 m/s to the nearest tenth of a m/s.

The measure of average velocity is a vector. Average velocity is calculated by dividing the change in position or displacement (x) by the time intervals (t) during which the displacement takes place. Depending on the direction of the displacement, the average velocity may be positive or negative. Meters per second (m/s or ms-1) is the SI unit for average speed.

Only the object's displacement is considered when calculating average velocity. However, the displacement's size might differ from the actual path's length. For this reason, we use average speed to describe the rate of motion along a path.

Average speed is calculated by dividing the total distance travelled by the total motion time. The average speed is a scalar quantity, in contrast to the average velocity.

Given distance: 248

and = 345 m

Time for both= 130 s

We know that average velocity = Distance + Distance  / time

Therefore,

Average velocity = (248 + 97) / (130)
