Answer:

There are different answers to that, like if you read a passage or something.

Explanation:

These days many people do not get exercise. A lot of jobs are now done indoors and do not require any physical activities. Technology is becoming more advanced and many people prefer using machines to do the heaving lifting.

There are a lot of fast-food restaurants and this is where a lot of people in the US choose to eat. The food is cheap and easy to pick up. This food is convenient for people on the go. The food is not healthy and it causes weight gain.

In the US, many young children find it cool to smoke. Smoking decreases the body's strength and it causes a decrease in physical health, causing people to gain weight.

Everyone has a phone these days, if not some kind of electronic device to chat with people or play games. Over time, playing on electronic devices replaces doing physical activities.

For the right block to balance the forces and remain steady, it needs to weigh 7.9 kg.

The force is an external agent which is applied to the body or an object to move it or displace it from one position to another position.

When there is no net force acting on the system, the two blocks stay in place. In this instance, the strain in the rope holding the two blocks together balances the pull of gravity on them. The sine of the angles, along with the masses of the blocks, can be used to calculate the tension in the rope.

\(T= (m_1 \times g) \times sin(\theta_1) + (m_2\times g) \times sin(\theta_2)\)

Substituting the known values:

\(T = (10 \times 9.8 )\times sin(23^o) + (m_2\times 9.8 )\times sin(40^o)\)

Solving for m₂:

\(m_2= \dfrac{(T- (10 \times 9.8 )\times sin(23^o)} { (9.8\times sin(40^o))}\)

The mass of the right block must be 7.9 kg for the two blocks to remain stationary.

To determine the distance spanned by the diffraction spot, we need to consider the properties of the diffraction pattern and the given information.

Given:

- The screen is 30 cm behind the fish.

- The entire path of the laser, including the water and tissue, has an index of refraction close to that of water.

- The properties of the diffraction pattern are determined by the wavelength in water.

Since the diffraction pattern is formed by the interaction of light waves with obstacles or apertures, the spot's size or spread depends on factors such as the wavelength of light and the size of the aperture.

Without specific information about the wavelength or aperture size, it is not possible to determine the exact distance spanned by the diffraction spot. Additional details regarding the specific setup or measurements would be necessary to calculate or estimate the distance spanned by the diffraction spot.

Saturn's rings are composed of primarily ice particles, ranging in size from tiny grains to large boulders.

There are also some traces of rock and dust mixed in with the ice particles. The rings are divided into several different groups, each with their own unique composition and characteristics.

The exact composition of the particles in the rings is not fully understood, but they are believed to be predominantly made of water ice, with some amount of rocky material mixed in.

The particles in the rings are spread out over a wide range of distances from Saturn, with the innermost ring starting at a distance of about 6,630 km (4,120 miles) from Saturn's cloud tops, and the outermost ring extending to a distance of about 120,700 km (75,000 miles). The rings are also very thin, with an average thickness of only about 10 meters (33 feet).

The origin of Saturn's rings is still a matter of scientific debate, but it is thought that they may be the remnants of a small moon or moons that were destroyed by tidal forces as they orbited Saturn. Another theory is that the rings are the result of a collision between two moons in the past.

The new repulsive force acting on the charges will be sixteen times greater than the original force.

According to Coulomb's law, the repulsive force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Therefore, if the distance between the charges is reduced to one-fourth of its original value, the force between them will increase by a factor of (1/0.25)² = 16.

In summary, bringing the two charges closer together so that their separation is one-fourth as great will result in a sixteen-fold increase in the repulsive force acting on them.

Mass of the merry-go-round (m): 105 kg

Radius of the merry-go-round (r): 2.3 m

Frequency of rotation (f): 0.56 rev/s

To solve the problem, we can calculate the angular velocity (ω) and the moment of inertia (I) of the merry-go-round.

The angular velocity (ω) is given by the formula:

ω = 2πf

Using the given frequency, we can calculate the angular velocity as:

ω = 2π(0.56 rev/s)

Next, we can calculate the moment of inertia (I) of the merry-go-round using the formula:

I = 0.5mr²

Substituting the given mass and radius into the formula, we have:

I = 0.5(105 kg)(2.3 m)²

Now, let's calculate the values:

Angular velocity:

ω = 2π(0.56) ≈ 3.518 rad/s

Moment of inertia:

I = 0.5(105)(2.3)² ≈ 273.23 kg·m²

Therefore, the merry-go-round is rotating with an angular velocity of approximately 3.518 rad/s, and it has a moment of inertia of approximately 273.23 kg·m².

Let's explain why Common Emitter (CE) configuration is preferred over Common Collector (CC) for amplification purposes.

Common Emitter amplifier is an amplifier that offers high current gain, medium input resistance and high output resistance.

Common Collector is another type of amplifier where the input signal is applied to the base and the ouput signal is taken from the emitter.

The Common Emitter configuration is preferred over the Common Collector configuration because the Common Emitter offers a high power gain(high voltage and current gain), and has a lower resistance when compared to the Common Collector configuration.

ANSWER:

The common Emitter configuration has higher voltage and current gain when compared to the Common Collector configuration.

The change in frequency in the echo is approximately 1125 Hz.

The Doppler effect describes the change in frequency of a wave as observed by an observer moving relative to the source of the wave. The formula to calculate the change in frequency is:

Δf/f₀ = (v/c) * f₀

where:

Δf is the change in frequency

f₀ is the original frequency

v is the velocity of the object

c is the speed of light

Given:

Original frequency (f₀) = 6.00 × 10^9 Hz

Velocity of clouds (v) = 8.52 m/s

Speed of light (c) = 3.00 × 10^8 m/s

Substituting the values into the formula, we have:

Δf/6.00 × 10^9 Hz = (8.52 m/s / 3.00 × 10^8 m/s) * 6.00 × 10^9 Hz

Simplifying the equation, we find:

Δf = (8.52 m/s / 3.00 × 10^8 m/s) * 6.00 × 10^9 Hz

Δf ≈ 0.01896 Hz

Converting to Hz, we get:

Δf ≈ 18.96 Hz

However, the change in frequency is given by the absolute value of Δf:

|Δf| ≈ |18.96 Hz| ≈ 18.96 Hz

Approximately, the change in frequency in the echo is 18.96 Hz.

The change in frequency in the echo, due to the clouds moving away at 8.52 m/s, is approximately 18.96 Hz.

(a) We can find the components of the acceleration of the fish by using the following kinematic equation:

v = u + at

where u is the initial velocity, v is the final velocity, a is the acceleration, and t is the time interval.

Let's find the acceleration of the fish in the x-direction first:

v_x = u_x + a_xt

where v_x is the x-component of the final velocity, u_x is the x-component of the initial velocity, a_x is the x-component of the acceleration, and t is the time interval.

Substituting the given values, we get:

23.0 = 4.00 + a_x * 19.0

Solving for a_x, we get:

a_x = (23.0 - 4.00) / 19.0 = 0.895 m/s^2

Similarly, we can find the acceleration of the fish in the y-direction:

v_y = u_y + a_yt

where v_y is the y-component of the final velocity, u_y is the y-component of the initial velocity, a_y is the y-component of the acceleration, and t is the time interval.

Substituting the given values, we get:

-1.00 = 1.00 + a_y * 19.0

Solving for a_y, we get:

a_y = (-1.00 - 1.00) / 19.0 = -0.105 m/s^2

Therefore, the components of the acceleration of the fish are:

a_x = 0.895 m/s²

a_y = -0.105 m/s²

The rate of change of velocity of an object over the course of time is defined as acceleration.  It is a vector quantity, that also means it has magnitude as well as direction. Acceleration occurs when an object changes its velocity, either by increasing or decreasing its speed or by changing its direction of motion. The following formula may be utilized to calculate an object's acceleration:

a = (v_f - v_i) / t

(b) To find the direction of the acceleration with respect to unit vector î, we can use the following formula:

θ = tan⁻¹(a_y / a_x)

Substituting the values we just found, we get:

θ = tan⁻¹(-0.105 / 0.895) = -6.84°

Therefore, the direction of the acceleration with respect to unit vector î is 6.84° clockwise from the +x-axis.

(c) To find the position of the fish at t = 26.0 s, we can use the following kinematic equations:

x = u_xt + 0.5 a_xt²

y = u_yt + 0.5 a_yt²

where x is the position in the x-direction, y is the position in the y-direction, u_x is the initial velocity in the x-direction, u_y is the initial velocity in the y-direction, a_x is the acceleration in the x-direction, a_y is the acceleration in the y-direction, and t is the time interval.

Let's first find the position of the fish in the x-direction:

x = u_xt + 0.5 a_xt²

Substituting the given values, we get:

x = 14.0 + 0.5 * 0.895 * (26.0 - 19.0)² = 37.4 m

Similarly, we can find the position of the fish in the y-direction:

y = u_yt + 0.5 a_yt²

Substituting the given values, we get:

y = -2.80 + 0.5 * (-0.105) * (26.0 - 19.0)²= -3.17 m

Therefore, the fish is at the position (37.4 m, -3.17 m) at t = 26.0 s.
