Answer:

\(1\times 10^{8} N/C\)

Explanation:

According to the gauss law

As we know that

Electric field is

\(E = -k\frac{q}{r^2}\)

where,

k = column constant = \(9 \times 10 ^{9}\ N. \frac{m^2}{c^2}\)

q = charge

r = distance from the sphere center

For computing the magnitude of e first we have to need to find out the charge outside of sphere which is

\(q = -\frac{Er^2}{k}\)

\(q = -\frac{1 \times 10^{6} \frac{N}{C} (25m)^2}{9 \times 10 ^{9}\ N. \frac{m^2}{c^2}}\)

q = -0.07 C

Now we have to find the electric field

\(E = k\frac{q}{r^2}\)

The r is 2.5m but in question it is given 5m

So,

Electric field is

\(E = 9 \times 10^{9} N . \frac{m^2 \times 0.07 C}{C^2 (2.5 m)^2}\)

\(E = 9 \times 10^{9} N. \frac{m^2 \times 0.07 C} {C^2 (2.5m)^2}\)

\(= 1\times 10^{8} N/C\)

The volume of the solid obtained by rotating the region under the curve y = 4 - 2√x from x = 0 to x = 2 about the x-axis is approximately 11.78 cubic units.

To find the volume of the solid, we can use the method of cylindrical shells. Considering a small vertical strip of width dx at a distance x from the y-axis, the height of the strip is given by y = 4 - 2√x.

The circumference of the shell is 2πx, and the thickness of the shell is dx. Therefore, the volume of each cylindrical shell is given by dV = 2πx(4 - 2√x)dx.

To obtain the total volume, we integrate this expression over the interval x = 0 to x = 2:

V = ∫[0 to 2] 2πx(4 - 2√x)dx

Simplifying and evaluating this integral, we find that the volume of the solid is approximately 11.78 cubic units.

Explanation:

The efficiency of the pulley system can be given as follows:

\(\eta = \frac{W_{out}}{W_{In}}\\\\\)

where,

η = efficiency of pulley system = ?

W_out = Output Work = (600 N)(0.6 m) = 360 J

W_in = Input Work = (35.7 N)(11.43 m) = 408.051 J

Answer:

v=10.78 m/s

Explanation:

Given that,

The student estimates that  the apple traveled 1.1 seconds straight down to the ground. We need to find the maximum velocity of the apple before it hit the ground. The initial velocity of the apple is equal to 0 as it was at rest. It will move under the action of gravity.

Using equation of motion to find it as follows :

v=u+at

a = g

⇒v=gt

v=(9.8 m/s²) × (1.1 s)

v = 10.78 m/s

So, the maximum velocity of the apple is 10.78 m/s.

The resistance of the electric appliance is 16 ohms. To determine the resistance of the electric appliance, we can use Ohm's law.

It states that the voltage (V) across a circuit element is equal to the product of the current (I) flowing through the element and the resistance (R) of the element.

Mathematically, Ohm's law can be expressed as:

V = I * R

We know that the current drawn by the appliance is 1.5 amperes, and the voltage source is 24 volts. Substituting these values into the equation, we get:

24 = 1.5 * R

Solving for R, we can divide both sides of the equation by 1.5, giving:

R = 16

Answer:

U-235

Explanation:

a rare needed compound

Answer:

You lift weights and train on a daily basis?

Explanation:

The gravitational force between the two masses is approximately 1.96 x 10⁻⁹ N. Option B is correct.

The gravitational force between two masses can be calculated using the formula;

F=G x (m₁ x m₂) / r²

Where F is the gravitational force, G is the gravitational constant, m₁ and m₂ are the masses of the two objects, and r is the distance between their centers of mass.

In this case, m₁ = 4.0 kg, m₂ = 7.0 kg, r = 1.0 m, and G = 6.67 x 10⁻¹¹ N x m²/kg². Plugging these values into the formula gives;

F = (6.67 x 10⁻¹¹ N x m²/kg²) x (4.0 kg x 7.0 kg) / (1.0 m)²

F = 1.96 x 10⁻⁹ N

Therefore, the gravitational force is 1.96 x 10⁻⁹ N.

Hence, B. is the correct option.

Hello!

We can use the following relationship:

\(\Delta KE = W = F \cdot d\)

ΔKE = Change in Kinetic Energy (J)
W = Work done on object (J)

F = Force (N)

d = distance of which the force is applied to the object. (This is equivalent to the length of the gun barrel, or 0.8 m)

Also, recall that:
\(KE = \frac{1}{2}mv^2\)

m = mass of bullet (0.02 kg)

v = velocity of bullet (vfinal = 985 m/s, vinitial = 0 m/s)

We can now solve.

\(\Delta KE = F \cdot d\\\\KE_f - KE_i = F \cdot d\\\\\frac{1}{2}(0.02)(985^2) - \frac{1}{2}(0.02)(0^2) = (0.8)F\\\\9702.25 = 0.8F\\\\F = \frac{9702.25}{0.8} = \boxed{12127.813 N}\)

Answer:

the answer is b, calcium-45

Explanation:

A phase change occurs when a substance changes from one state of matter to another.

A scene in which at least two phase changes take place is when ice is converted to vapor.

To convert ice to vapor, we need to supply energy to the ice in form of heat. The molecules in the ice begin to move faster as they acquire more energy and eventually the lattice falls apart and ice is converted to liquid.

As more energy is supplied, the molecules acquire even greater energy and move at higher speeds, all the intermolecular bonds between the molecules are severed as the liquid turns into vapor.
