(a) what was the acceleration of each sprinter? (b) what were their respective maximum speeds? (c) which sprinter was ahead at the 6.00-s mark, and by how much?

### Answers

You should now use t2 at 4s instead of Maggie's t1, which is still at 2s (to add up to 6s). Judy's T1 and T2 each last three seconds. A net force acts to change the **motion** of an object; the increased the net force, the greater the acceleration.

**What does acceleration truly mean?**

Acceleration is the change in a moving object's **speed** and direction over time. Something is said to be accelerating when it starts to move faster or slower.

**What precisely are acceleration and speed?**

The measurement of velocity is the rate at which a displacement changes. What determines how rapidly a velocity changes is acceleration. Due to the fact that both **magnitude** and direction are a part of velocity, it is a vector quantity. A vector quantity is also acceleration.

**Briefing:**

(a) You may now solve for each runner's acceleration using this equation by entering the proper numbers for each runner. (For Judy, t1=3s & t2=7.2s; for Maggie, t1=2s & t2=8.2s).

(b) Refer back to our first equation:

100m = 0.5*a*t12 + v*t2

(c) Rewrite the first equation as follows:

Δx = 0.5*a*t12 + v*t2

Now, for each runner, solve for x. Maggie's t1 remains at 2s, but you should now use t2 at 4s (to add up to 6s). T1 and T2 are 3 seconds for Judy.

what happens to the atomic radius as you move across a period from left to right?

### Answers

**Atomic radius** typically increases down a group and decreases over a period. Effective nuclear charge rises with time while electron shielding stays constant.

Why does the atomic radius shrink from left to right?

As the **electrons **in the final shell are drawn toward the higher nuclear charge, the atoms become smaller. As a result, the size gets smaller from left to right.

Why, according to Brainly, does the atomic radius shrink as you walk across a period from left to right?

The atomic number grows as we move from left to right in a period, but the shell stays the same, which causes electrons to be added in the same shell, increasing the force of **attraction **between the electrons and the nuclei.

A 61.0 kg sled is pulled from rest by a snowmobile and accelerates at 2.4 [forward] for 5.5 s. The force of friction acting on the sled is 111.0 N [backwards]. The total mass of the snowmobile and the driver is 461.0 kg and the force of friction acting on the snowmobile is 546.0 N [backwards]. Determine the power developed by the snowmobile engine.

### Answers

**Answer:**

1922.8 watts

**Explanation:**

To find the power developed by the snowmobile engine, we first need to determine the force that the snowmobile is applying to the sled. We can use Newton's second law to do this. The equation for Newton's second law is:F = maWhere F is the force applied, m is the mass, and a is the acceleration. We can rearrange this equation to solve for the force applied by the snowmobile:F = ma = (61.0 kg)(2.4 m/s^2) = 146.4 N [forward]Now that we know the force applied by the snowmobile, we can use the equation for power to determine the power developed by the snowmobile engine:P = FvWhere P is the power, F is the force applied, and v is the velocity. We don't know the velocity of the sled, but we do know that the sled accelerates at a rate of 2.4 m/s^2 for 5.5 seconds. We can use this information to find the velocity of the sled at the end of the 5.5 seconds:v = atWhere v is the velocity, a is the acceleration, and t is the time. Substituting the values from the problem gives us:v = (2.4 m/s^2)(5.5 s) = 13.2 m/sNow that we know the velocity of the sled, we can substitute this value into the equation for power to find the power developed by the snowmobile engine:P = (146.4 N)(13.2 m/s) = 1922.8 wattsTherefore, the power developed by the snowmobile engine is 1922.8 watts.

the **mass** of the photon(m) is = 5.1 × 10⁻²⁶ Kg .

we know that , k = m*ω²

Substituting the values ,

we get ,

24 = (5.1 × 10⁻²⁶)*ω²

Simplifying further ,

we get ,

ω = 2.1693 × 10¹³ rad/sec .

the **formula **for the **energy **of the photon is given as

Eₙ = hω(n + 1/2) ...where h(planks constant) = 6.63 × 10⁻³⁴

the energy of photon when it is **dropped** from energy **level 9** to energy **level 4** is given by :

E₉ - E₄ = hω(9 + 1/2 - 4 - 1/2)

= hω(5)

Converting the value of ω , and substituting it in the equation ,

we get ,

= 5/2π × (6.63 × 10⁻³⁴) × (2.1693 × 10¹³)

On simplifying the above equation further ,

we get ,

= 1.14 × 10⁻²⁰ Joules .

Therefore , the **energy **of the **photon **is 1.14 × 10⁻²⁰ Joules .

The given question is incomplete , the complete question is

gas moves from an area of ________ partial pressure to an area of ________ partial pressure.

### Answers

From one region of high **partial** pressure to another region of low partial pressure, a gas moves. It travels toward the lower pressure area because the higher pressure area has more relative energy.

What does it indicate when a gas has a partial pressure?

When more than one gas is present in a container, each gas exerts **pressure**, which is known as partial pressure. Its partial pressure refers to the pressure of any gas inside the container.

What distinguishes pressure from partial pressure?

The main distinction between a gas's vapor pressure and partial pressure is that the former refers to the pressure the gas is exerting over its condensed phase, whilst the latter refers to the pressure the gas is exerting in volume.

What happen to the ma of the object if the coefficient of kinetic friction were to increae?

### Answers

When the **coefficient of kinetic friction** is increasing means, the** mass** of the object is also increasing, so the **normal force** acting between the contact surfaces will also increase, ultimately increasing the **friction**.

What is the Coefficient of kinetic friction?

The ratio obtained by dividing the force required to keep an object moving by the force keeping two sliding surfaces together is known as the **coefficient of kinetic friction**. The materials used to create the contacting surfaces are particular to this coefficient. The coefficient will be higher on a rougher surface. The ratio of both the friction force to the normal force felt by a body moving on a dry, uneven surface is known as the kinetic friction coefficient or μk.

What is Friction?

The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction. There are various kinds of friction, two solid surfaces in touch are opposed to one another's relative lateral motion by dry **friction**.

Hence, when the **coefficient of kinetic friction** is increasing means, the **mass** of the object is also increasing, so the **normal force** acting between the contact surfaces will also increase, ultimately increasing the **friction**.
