A particular star cluster contains stars all with the same apparent magnitude of +4. Near the cluster (and at the same distance
777dan777 [17]

Answer:

3,000 stars.

Explanation:

Subtract the magnitude of the single star from the magnitude of the star cluster.

(+4) - (+1) = +3

Then multiply your answer by 1000

= 3,000 is a stars.

A proton has a charge of 1.6 × 10-19 C and a mass of 1.67 × 10-27 kg. A proton moves with velocity 1.8 × 105 m/s in the z-direct
lord [1]

Hey

So first we need to know what the direction of the force is, using your right hand rule point your right hand in the direction of the velocity. You're saying its the z direction, not telling me whether it's into the page or out? Since its a positive z im assuming its coming out. The magnetic field is pushing it upwards, so the force is going in the negative x direction.

The force of a magnetic field is

F = Qv X B

What's weird is that you don't need mass in this equation. Actually you don't even need the formula, its telling you that they're all going in perpendicar directions. the answer is 90 degrees.

Now if you want to know the F just multiply the charge, velocity and magnetic field .

F = GVB

F = 6.048 E -15

Answer : 90 degrees, sin(90) = 1

81. A 560-g squirrel with a surface area of 930cm2 falls from a 5.0-m tree to the ground. Estimate its terminal velocity. (Use a
Irina18 [472]

Answer:

Explanation:

Given

mass of squirrel m=560 gm

Surface area of squirrel A=930 cm^2

and the area which face A_f=\frac{A}{2}=465 cm^2

height of tree h=5 m

Coefficient of drag C=1

drag Force F_d=\frac{1}{2}C\cdot \rho \cdot A\cdot v^2

Terminal velocity is given

F_d=mg

\frac{1}{2}C\cdot \rho \cdot A\cdot v^2=mg

v=\sqrt{\frac{2\times m\times g}{\rho \times C\times A_f}}

v=\sqrt{\frac{2\times 0.560\times 9.8}{1.2\times 1\times 465\times 10^{-4}}}

v=13.9 m/s

(b)Mass of person m=56 kg

v^2-u^2=2gh

u=0

v=\sqrt{2gh}

v=\sqrt{2\times 9.8\times 5}

v=9.89 m/s
