Answer:

2. at the highest point

Explanation:

For a generic object, the PE (gravitational potential energy) is defined as

PE = mgh

where

m is the mass of the object

g is the gravitational acceleration

h is the height of the object with respect to the ground

From the formula, we see that PE is maximum when h is maximum: so the PE is maximum when the object is at the highest point.

Choose all the answers that apply. Power is calculated using ___.
antiseptic1488 [7]

Time , Work, Horsepower

Explanation:

In General, Power is defined as rate of doing work in physics.

1.) By work and Time, we can calculate power as follows,

                 Power = Work done per unit Time

                              = Work done / time

2.) From Horsepower we can directly get the power.

Horsepower (hp) is a unit to measure the  power, or the rate at which work is done, usually in  the output of engines or motors. There are many  types of horsepower. Two common ways of defining horsepower is being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.

A deuteron particle consists of one proton and one neutron and has a mass of 3.34x10^-27 kg. A deuteron particle moving horizont
nikklg [1K]

_dThe radius of curvature of a subatomic particle under a magnetic field is given by the following formula:

r=\frac{mv}{qB}

Where:

\begin{gathered} r=\text{ radius} \\ v=\text{ velocity} \\ q=\text{ charge} \\ B=\text{ magnetic field} \end{gathered}

We can determine the quotient between the velocity and the charge of the deuteron particle from the formula. First, we divide both sides by the mass:

\frac{r_d}{m_d}=\frac{v}{q_B_}

Now, we multiply both sides by the magnetic field "B":

\frac{Br_d}{m_d}=\frac{v}{q}

Since the charge of the deuterion is the same as the charge of the proton and the velocity we are considering are the same this means that the quotient between velocity and charge is the same for both particles. Therefore, we can apply the formula for the radius again, this time for the proton:

r_p=\frac{m_pv}{qB}

And substitute the quotient between velocity and charge:

r_p=\frac{m_p}{B}(\frac{Br_d}{m_d})

Now, we cancel out the magnetic field:

r_p=\frac{m_pr_d}{m_d}

Now, we substitute the values:

r_p=\frac{(1.67\times10^{-27}kg)(0.385m)}{(3.34\times10^{-27}kg)}

Solving the operations:

r_p=0.193m=19.3cm

Therefore, the radius is 19.3 cm.

Brums [2.3K]

Answer:

h = 81.63 m

Explanation:

Given that,

The speed of the car, v = 40 m/s

We need to find the height when the car comes to rest. We can use the conservation of energy to find it i.e.

mgh=\dfrac{1}{2}mv^2\\\\h=\dfrac{v^2}{2g}\\\\h=\dfrac{(40)^2}{2\times 9.8}\\\\h=81.63\ m

So, it will reach to a height of 81.63 m and comes to rest.
