Answer:

0.545 m

Explanation:

K. E = 26 MeV = 26 x 1.6 x 10^-13 J = 4.16 x 10^-12 J

B = 1.35 T

Let r be the radius of curvature

The formula for the kinetic energy of a cyclotron is given by

K.E. = \frac{B^{2}q^{2}r^{2}}{2m}

m = 1.67 x 10^-27 kg, q = 1.6 x 10^-19 c

4.16\times 10^{-12} = \frac{1.35^{2}\times (1.6\times 10^{-19})^{2}r^{2}}{2\times 1.67\times 10^{-27}}

r = 0.545 m

Write a complete scientific explanation to account for why the ball that was moving faster caused more flour to spread out.​
Harlamova29_29 [7]

Answer:

It is due to the large impulse is imparted on the flour.

Explanation:

A ball is moving faster.

When a ball is moving faster strikes to the flour, the change in momentum is large and thus the impulse imparted on the flour is large.

Impulse = change in momentum

So, as the flour experiences large impulse and large momentum so that the flour spreads out.

If the change in momentum is large so the flour spreads out is more.

The Earth has a speed of 108,064.5 km/hr around the sun. The planet Mars has a speed of 86,868 km/hr around the sun.
Leni [432]

Answer:

Graph B

Explanation:

This is because the full question is "The Earth has a speed of 108,064.5 km/hr around the sun. The planet Mars has a speed

of 86,868 km/hr around the sun. Which of the following graphs best represents the

motion of the two planets?" The answer would be B because the more steeper the slope means more speed.

A student wanted to determine the evaporation rates of liquids. She placed 50 mL of each liquid outside for an hour on the same
WARRIOR [948]

Answer:

without answers to choose from, I'd say make sure you're using the same shape and sized containers, and they're placed in the same locations at the same time. also you'd probably get a more accurate result by leaving them longer than an hour, more like a day or 2, and do it on multiple different days, when the temperature is different each day and then take an average of those days...

One ounce of a well-known breakfast cereal contains 103 Calories (1 food Calorie = 4186 J). If 1.6% of this energy could be conv
faust18 [17]

Answer:

the heaviest barbell that could be lifted  is 390.6kg

Explanation:

Hello!

To solve this question you must follow the following steps

1. Find the amount of energy that can transform the body into motion, this is achieved by multiplying the breakfast consumed by the percentage of energy conversion.

W=(103Calories)(0.016)\frac{4186J}{1calorie} =6898.5J

2. We use the equation that defines the work done by a body that has weight when it is lifted, this is defined by the product of mass by gravity by height.

W=mgh

where

W=work=6898.5J

m=mass

g=gravity=9.81m/s^2

h=height=1.8m

now we solve for mass, and use the values.

m=\frac{W}{hg} =\frac{6898.5}{(1.8)(9.81)} =390.6kg

the heaviest barbell that could be lifted  is 390.6kg
