A proton enters a magnetic field (B = 5.00 x 10^-2 T INTO THE PAGE) with

Physics

Answer:

r = 1.16 m

Explanation:

It is given that,

Magnetic field, B=5.6\times 10^6\ m/s

Velocity of proton, v=5.6\times 10^6\ m/s

We need to find the radius (in m) of the  circular path the particle will follow when it is travelling within the  magnetic field. The radius followed by the proton is given by :

r=\dfrac{mv}{qB}

m is mass of proton, m=1.67\times 10^{-27}\ kg

So,

r=\dfrac{1.67\times 10^{-27}\times 5.6\times 10^6}{1.6\times 10^{-19}\times 5\times 10^{-2}}\\\\r=1.16\ m

So, the radius of circular path is 1.16 m.

Which of the following statements are true concerning the creation of magnetic fields? Check all that apply. Check all that appl
Andreas93 [3]
<h3><u>Answer;</u></h3>
  • A moving electric charge creates a magnetic field at all points in the surrounding region.
  • An electric current in a conductor creates a magnetic field at all points in the surrounding region.
  • A permanent magnet creates a magnetic field at all points in the surrounding region.
<h3><u>Explanation;</u></h3>
  • A magnetic field can be created by running electricity through a wire. All magnetic fields are created by moving charged particles. it is important to also note that charged particles create magnetic fields only when they are moving.
  • The strength of the magnetic field generated or created is proportional to the amount of current flowing through the wire. Thus, increasing the current increases the strength of the magnetic field.

A boy throws a baseball onto a roof and it rolls back down and off the roof with a speed of 4.05 m/s. If the roof is pitched at
AlekseyPX

(a) The time the baseball spends in the air is 0.92 s.

(b) The horizontal distance from the roof edge to the point where the baseball lands on the ground is 3.1 m.

<h3>Time spent in air by the baseball</h3>

h = vt - ¹/₂gt²

-2.1 = (4.05 x sin 34)t  - ¹/₂(9.8)(t²)

-2.1 = 2.26t - 4.9t²

4.9t² - 2.26t - 2.1 = 0

t = 0.92 s

<h3>Horizontal distance traveled by the baseball</h3>

R = Vx(t)

R = (4.05 x cos 34)(0.92)

R = 3.1 m

Thus, the time the baseball spends in the air is 0.92 s.

The horizontal distance from the roof edge to the point where the baseball lands on the ground is 3.1 m.

10 points) A rubber ball and a lump of putty of the same mass m = 0.05 kg are thrown with the same speed v=10.0 m/s in positive
snow_lady [41]

Answer:

the ball experiences the greater momentum change

Explanation:

You have to take into account that momentum change is given by

\Delta p=mv_f-mv_b

where vf and vb are the speed of the object after and before the impact.

In the case of the ball you have

\Delta p=(0.05kg)(-10.0\frac{m}{s})-(0.05kg)(10.0\frac{m}{s})=-1kg\frac{m}{s}

where the minus of vf is included due to the motion is in an opposite direction regarding with vb

And for the lump

\Delta p=(0.05kg)(10.0\frac{m}{s})-(0.05kg)(0\frac{m}{s})=0.5kg\frac{m}{s}

Hence, the ball experiences the greater change

hope this helps!!

A gas bottle contains 0.650 mol of gas at 730 mm Hg pressure. If the final pressure is 1.15 atm, how many moles of gas were adde
AlekseyPX

Answer:

0.779 mol

Explanation:

Since the gas is in a bottle, the volume of the gas is constant. Assuming the temperature remains constant as well, then the gas pressure is proportional to the number of moles:

p \propto n

so we can write

\frac{p_1}{n_1}=\frac{p_2}{n_2}

where

p1 = 730 mm Hg = 0.96 atm is the initial pressure

n1 = 0.650 mol is the initial number of moles

p2 = 1.15 atm is the final pressure

n2 is the final number of moles

Solving for n2,

n_2 = n_1 \frac{p_2}{p_1}=(0.650 mol)\frac{1.15 atm}{0.96 atm}=0.779 mol
