In the lab, a relativistic proton has a momentum of 1.00 ×10^-19 kg ∙ m/s and a rest energy of 0.150 nJ. What is the speed of the proton in the lab? (c = 3.00 × 10^8 m/s, mass of proton = 1.67 ×10^-27 kg)

Find the equation, the center and the radius of a circle passing through (1,-3) , (2,-2) and (-2,6).... with steps.

What is the purpose of control in a scientific experiment.

State the cell theory as we understand it today.

For the company to lose money, p(x)<0 We have: p(x)=x(15000-750x) And since x is the number of items produced ==> x>0 Thus, 15000-750x<0; 750x>15000; x>20 Therefore, the company loses money for x>20 items

At the beginning, he had 10 coins and drew one. For this one to be a dime, it has a probability of 5/10 (5 dimes out of 10 coins in total). So p1=1/2 Then, after drawing that coin, he has 9 total coins in his pocket, then he drew one. For this coin to be...

Let the three pieces of the rope be x,y, and z respectively. 1) x=2y 2) z=3y (Note: We deduce from these 2 equations that the longest part we want to find is z) 3) x+y+z=120 Substitute 1) and 2) in 3) Hence we get: 2y+y+3y=120; 6y=120 ==> y=20 ft Therefor...

(sin theta)^2+(cos theta)^2=1; (sin theta)^2+1/10=1; (sin theta)^2=9/10 sin theta= 3/(sqrt10) OR sin theta=-3/(sqrt10) But since theta is a first quadrant angle ==> sin theta is positive Therefore, sin theta= 3/(sqrt10)

This is a simple problem of solving 2 equations with 2 unknowns: 1) 4blue + 5yellow = 49 2) 2blue + 1yellow = 17 Multiply equation 2) by 2: 2) 4blue + 2yellow = 34 Now, subtract 2) from 1): (4blue + 5yellow) - (4blue + 2yellow) = 49 - 34; 3yellow = 15; ye...

I can't get it! What is the question here?! Is it 677/7=?

It is accelerating. Otherwise, it would be moving in a straight line. As long as there's a change in direction, there's acceleration. What we have here is that the magnitude of the velocity (speed) is constant, but the direction keeps changing over time....

m<SUT فأوجد، m<SUT=(3x+6),m<RUS=(5x-4) اذا كان

why you multiply x+2 by 2?????
