tortoises are ectotherms , but it is inaccurate to describe them as cold blooded because their blood would actually be quite warm. this is especially true of mainland tortoises, whose high surface area/volume ratios could cause them to lose heat so slowly that their body temperature could be elevated well above ambient temperature.

The statement "in a hurricane the greatest wind speeds and heaviest rainfall occur in the region called the eye" is false. In fact, the eye is typically a relatively calm and clear area at the center of the storm.

In a hurricane, the greatest wind speeds and heaviest rainfall do not occur in the region called the eye. The eye of a hurricane is a circular area of calm, surrounded by a circular wall of clouds and thunderstorms called the eyewall. The eyewall is where the most intense and destructive weather occurs, including the strongest winds and heaviest rainfall.

The reason for this is that the eyewall is where the strongest updrafts and downdrafts occur, which are caused by the intense convection of warm, moist air rising from the ocean's surface. This convection produces the thunderstorms and cloud formations that are characteristic of a hurricane. The rising air in the eyewall creates low pressure, which draws in air from the surrounding areas, leading to strong winds.

Answer:

gravityis an invisible force that pulls objects toward each other. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass .

Sure! Here are the steps for calculating the velocity and distance traveled by the car after 50 seconds :

Step 1: Calculate the velocity using the equation:

\(v = u + at\)

where:

- \(v\) is the final velocity

- \(u\) is the initial velocity (0 m/s, as the car starts from rest)

- \(a\) is the acceleration (3 m/s²)

- \(t\) is the time (50 seconds)

Substituting the values into the equation:

\(v = 0 + (3 \, \text{m/s²}) \times (50 \, \text{s})\)

Step 2: Calculate the distance traveled using the equation:

\(s = ut + \frac{1}{2}at^2\)

where:

- \(s\) is the distance traveled

- \(u\) is the initial velocity (0 m/s)

- \(a\) is the acceleration (3 m/s²)

- \(t\) is the time (50 seconds)

Substituting the values into the equation:

\(s = 0 \times (50 \, \text{s}) + \frac{1}{2} \times (3 \, \text{m/s²}) \times (50 \, \text{s})^2\)

Now, let's simplify these equations:

\(v = 3 \times 50\)

\(s = \frac{1}{2} \times 3 \times 50^2\)

Calculating the results:

\(v = 150\) m/s

\(s = 3750\) meters

Therefore, after 50 seconds, the car will have a velocity of 150 m/s and would have traveled a distance of 3750 meters.

Given:

A ball bouncing eventually comes to stop.

To find:

What kind of a system is this?

Explanation:

An open system is a system where the free exchange of matter and energy with the surroundings takes place.

A closed system is where only the energy of the system is shared with the surrounding. In these kinds of systems, the exchange of matter does not take place.

An isolated system is where neither matter nor energy is exchanged between the system and the surrounding.

When a ball is bouncing, it gradually loses its kinetic energy to the surroundings and eventually comes to stop. But the mass of the ball remains the same. Thus this is a closed system.

Final answer:

The given system is a closed system.

Therefore the correct answer is option B.

The magnitude of the acceleration experienced by an electron in an electric field of 750 N/C is approximately 1.318 × 10¹⁴ m/s².  

If the electric field is in the direction of positive x-axis, the electron will be accelerated in the negative x-axis direction. If the electric field is in the direction of positive y-axis, the electron will be accelerated in the negative y-axis direction, and so on.

The magnitude of the acceleration experienced by an electron in an electric field can be calculated using the formula:

a = F/m

where F is the force experienced by the electron in the electric field, and m is the mass of the electron.

The force experienced by an electron in an electric field is given by:

F = qE

where q is the charge of the electron, and E is the electric field strength.

The mass of an electron is approximately 9.11 × 10⁻³¹ kg, and the charge of an electron is -1.602 × 10⁻¹⁹ C.

Substituting these values, we get:

F = (-1.602 × 10⁻¹⁹ C) × (750 N/C) = -1.2015 × 10⁻¹⁶ N

a = F/m = (-1.2015 × 10⁻¹⁶ N) / (9.11 × 10⁻³¹ kg) ≈ -1.318 × 10¹⁴ m/s²

Therefore, the magnitude of the acceleration experienced by an electron in an electric field of 750 N/C is approximately 1.318 × 10¹⁴m/s².

The direction of the acceleration of the electron depends on the direction of the electric field at that point. By convention, the direction of the electric field is the direction in which a positive charge would experience a force. Since the charge of an electron is negative, the force experienced by an electron in an electric field is opposite in direction to the electric field.

If the pulley has 5 sections, it means that it is a block and tackle system with a mechanical advantage of 5. This means that the force required to lift the box is 1/5 of the weight of the box.

Force for each section = Force required to lift the box / Number of sections

Force for each section = 50 N / 5

Force for each section = 10 N

Therefore, the Newton of force for each section is 10 N.

The IMA (ideal mechanical advantage) of a pulley system is calculated by dividing the distance over which the effort force is applied by the distance over which the load is moved. Since the pulley system does not change the direction of the applied force, the IMA is simply equal to the number of sections in the pulley.

IMA = Number of sections

IMA = 5

The formula for IMA (ideal mechanical advantage) of a simple machine is:

IMA = Distance over which the effort force is applied / Distance over which the load is moved

In the case of a pulley system, the formula can be simplified to:

IMA = Number of sections

This is because the pulley system does not change the direction of the applied force, and each section of the pulley contributes to the mechanical advantage equally.

A horizontal force Fslide is exerted on a 9.0-kg box sliding on a polished floor, the box's speed is approximately 1.39 m/s.

To determine the box's speed at t = 5.0 s, we can use Newton's second law of motion, which states that the net force acting on an object is equal to its mass multiplied by its acceleration:

Fnet = m * a

In this case, the only force acting on the box is the horizontal force Fslide. Since there is no friction between the box and the floor, the net force is equal to the applied force:

Fnet = Fslide

We know that the magnitude of Fslide increases smoothly from 0 to 5.0 N in 5.0 s. This implies that the force is changing uniformly, and we can calculate its average value using the formula:

Favg = (Finitial + Ffinal) / 2

where Finitial is the initial magnitude of the force (0 N) and Ffinal is the final magnitude of the force (5.0 N).

Given:

m (mass of the box) = 9.0 kg

Finitial = 0 N

Ffinal = 5.0 N

t = 5.0 s

Using the formula for average force, we can calculate Favg:

Favg = (Finitial + Ffinal) / 2

Favg = (0 N + 5.0 N) / 2

Favg = 2.5 N

Now, we can use Favg and Newton's second law to find the acceleration (a) of the box:

Fnet = m * a

Favg = m * a

2.5 N = 9.0 kg * a

Solving for a:

a = 2.5 N / 9.0 kg

a ≈ 0.278 m/s²

With the acceleration value, we can determine the box's speed at t = 5.0 s by using the following kinematic equation:

v = u + a * t

where:

v is the final velocity (speed)

u is the initial velocity (speed), which is 0 m/s since the box starts from rest

a is the acceleration (0.278 m/s²)

t is the time (5.0 s)

Plugging in the values, we can calculate the speed at t = 5.0 s:

v = u + a * t

v = 0 m/s + 0.278 m/s² * 5.0 s

v ≈ 1.39 m/s

Therefore, the box's speed at t = 5.0 s, starting from rest, is approximately 1.39 m/s.

Mass of water, M = 125 g

Constant molar heat capacity of water, c2 = 75.29 J K⁻¹ mol⁻¹

Initial temperature of water, T2 = 25°C

Heat is transferred from the copper block to the water until both reach a common temperature, T. We are to find the change in entropy for each process using the following formula:

Change in entropy, ΔS = Q / T

where Q is the amount of heat transferred and T is the common temperature of the system. Since the process is reversible, we can also write this as:

ΔS = ∫ dQ / T

Change in entropy of copper block:

The amount of heat transferred from the copper block to the water, Q1 = mc1ΔT = (8.96/63.546) × 24.44 × (T - 85) J/K

where ΔT = T - T1 is the change in temperature.

Using the formula for change in entropy:

ΔS1 = Q1 / T = (8.96/63.546) × 24.44 × (T - 85) / T J/K

Change in entropy of water:

The amount of heat transferred from the copper block to the water is the same as the amount of heat gained by the water, Q2. So,

Q2 = -Q1 = -(8.96/63.546) × 24.44 × (T - 85) J
