Explanation:

When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the object

which means that it refers to transfer through a selectively permeable partition, the contact path.[1] For the relation of thermal equilibrium, the contact path is permeable only to heat; it does not permit the passage of matter or work; it is called a diathermal connection. According to Lieb and Yngvason, the essential meaning of the relation of thermal equilibrium includes that it is reflexive and symmetric. It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms

Americium-241  isotope would be expected to have the longest half-life. Hence, option (D) is correct.

In radioactivity, the half-life is the time required for one-half of a radioactive sample's atomic nuclei to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time required for the number of disintegrations per second of a radioactive material to decrease by one-half.

According to given data:

Rate of decay is the highest for Mercury-194, hence, its half-life is least. Then rate of decay is lowest for  Americium-241, hence, its half-life is the longest. Hence, option (D) is correct.

The order of half-life according to the data is:

Americium-241 > Silver-108 > Californium-249 >  Mercury-194.

Seagrasses are a vital part of the marine ecosystem..

Seagrasses are submerged flowering plants found in shallow marine waters, such as bays and lagoons and along the continental shelf in the Gulf of Mexico. A vital part of the marine ecosystem due to their productivity level, seagrasses provide food, habitat, and nursery areas for numerous vertebrate and invertebrate species. The vast biodiversity and sensitivity to changes in water quality inherent in seagrass communities makes seagrasses an important species to help determine the overall health of coastal ecosystems. Seagrasses perform numerous functions:

Stabilizing the sea bottom

Providing food and habitat for other marine organisms

Maintaining water quality

Supporting local economies

Explanation:

The total amount you'll end up paying is $8,119.78, which is more than the amount you're borrowing. This is because the interest on the loan adds up over time.

They are offering you a loan of $7,000 with an interest rate of 6.5%. The loan term is 48 months, which means you have four years to repay the loan.

Based on these terms, your monthly payments will be $170.41.

However, the total amount you'll end up paying is $8,119.78, which is more than the amount you're borrowing. This is because the interest on the loan adds up over time.

To put it simply, the dealership is lending you $7,000, but they are also charging you 6.5% interest on the amount you borrow. This means that for every month you keep the loan, you'll pay some interest, which adds up over time. By the end of the 48-month loan term, you'll have paid back the $7,000 you borrowed, plus the additional $1,119.78 in interest.

So, before you decide to accept the loan offer, it's important to understand the total cost of the loan and whether the monthly payments fit into your budget. You may also want to shop around and compare loan offers from different lenders to find the best deal for you.

Therefore, you'll have paid back the $7,000 you borrowed, plus the additional $1,119.78 in interest. which is greater than the borrowed.

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.

Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.

Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.  

v = d / t

Where v is the velocity, d is the distance covered and t is the time taken by the body.

The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).

Given, the distance traveled by the vehicle, d = 100 m

The time taken by vehicle = 0.246 sec

The velocity of the vehicle, v = 100/0.246 = 406.5 m/s

We know that 1km = 1000m then 1 m = 10⁻³ Km  

1 hour = 60 ×60 = 3600 s

1s = 1/3600 hr

Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)

v = 1463.4 Km/hr

Answer:

Explanation:

Answer:

The estimated braking force needed to stop the lorry is zero, based on the given information and calculations. However, it's important to note that this result is likely not accurate, as some force is required to stop a moving object. It's possible that additional information or calculations are needed to obtain a more realistic estimate of the braking force.

Explanation:

To estimate the braking force needed to stop the lorry, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).

In this case, the lorry decelerates uniformly, so the acceleration is constant. The initial velocity is assumed to be zero since the lorry comes to a stop. The final velocity is also zero. Therefore, we can use the equation:

Final velocity squared (vf^2) = Initial velocity squared (vi^2) + 2 * acceleration (a) * distance (d)

Since vi = 0 and vf = 0, the equation simplifies to:

0 = 0 + 2 * a * d

Solving for acceleration (a), we have:

2 * a * d = 0

a = 0

Since the acceleration is zero, it means that the braking force needed to stop the lorry is also zero. This is likely not an accurate result as some force is required to stop the lorry. It's possible that additional information or calculations are needed to accurately estimate the braking force.

The braking force required to stop a 6371 kg lorry after spotting a hazard and applying the brakes is what the question is asking for. The lorry decelerates uniformly and comes to a stop 60 meters after the brakes are applied.

The following steps will guide you on how to calculate the braking force:

Step 1: Determine the mass of the lorry which is 6371 kg. This will be denoted as m.

Step 2: Determine the distance travelled by the lorry, which is 60 m.

Step 3: Determine the time taken by the lorry to stop. This can be done by using the formula for uniform deceleration, which is a = (v-u)/t where v is the final velocity, u is the initial velocity and a is the uniform deceleration. Since the lorry comes to a stop, its final velocity is zero and its initial velocity is unknown.

However, we can assume that the lorry was initially travelling at a constant speed before spotting the hazard. Therefore, we can assume that the initial velocity was equal to the average velocity of the lorry before the brakes were applied.

This can be calculated using the formula v = d/t where d is the distance travelled and t is the time taken. The average velocity can therefore be calculated as follows: v = d/t = 60 m/t

Step 4: Rearrange the formula for uniform deceleration, a = (v-u)/t, to find u which is the initial velocity. Since the lorry comes to a stop, we know that v = 0.

Therefore: u = v - at where a is the uniform deceleration and t is the time taken to stop which is also equal to the time taken for the lorry to travel the distance of 60 meters. Substituting for v, we get: u = - at

Step 5: Calculate the acceleration of the lorry using the formula a = (v-u)/t. Since the final velocity is zero, we get: a = -u/t = -(-at)/t = a The acceleration is negative since the lorry is decelerating.

Step 6: Calculate the braking force using the formula F = ma where F is the braking force and m is the mass of the lorry. Therefore: F = ma = (-ma) since a is negative = (-6371 kg) (a) Therefore, the braking force required to stop the lorry is -6371a N where a is the uniform deceleration calculated in Step 5.

The correct answer is NO because the moon appearance is relatively base on the positioning of Sun - Earth - Moon

A moon is an opaque object. It does not give or illuminate light on its own, It reflects light from from the sun to the earth. The appearances of moon are;

In this activity, if you modeled the Sun–Earth–Moon system and you remove one object from this system model, would the model still explain the changes to the Moon’s appearance?

The answer is capital NO.

The reason is simply because the moon appearance is relatively base on the positioning of Sun - Earth - Moon relationship. That is, the moon appearances of waxing crescent, waxing gibbous, waning crescent and waning gibbous, all depend on the position of the Sun, Moon and the earth.

Therefore, If you removed one object from this system model, the model cannot explain the changes to the Moon’s appearance again.

The top of the circle

Explanation:

At the top of the circle, there are two forces pulling the ball towards the center of the circle: weight and tension.

∑F = ma

mg + T = mv²/r

As v goes down, T also goes down, until it eventually reaches 0.

At the bottom of the circle, weight is pulling down, or away from the center of the circle.  Sum of the forces:

∑F = ma

T − mg = mv²/r

As v goes down, T also goes down.  However, even at v=0, T cannot be less than mg.
