You will use the Pythagorean Theorem to solve it.
c^2 = a^2 + b^2
c^2 = (1.5)^2 + (2)^2
c^2 = 6.25
c = square root of 6.25
c = 2.5
I hope this helps!

Extra Credit: Show all your work to obtain credit. A beam of alpha particles ( q = +2e, mass = 6.64 x 10-27 kg) is accelerated f

andrezito [222]

Answer:

B = 0.036 T

Explanation:

Given:

$m = 6.64*10^-^2^7$

p.d, Va= 1.8 KV = 1800V

Distance btw plates, d= 8mm = 0.008m

$q = 2 * 1.6*10^-^1^9$

Let's use the equation:

$q*Va = \frac{1}{2} mv^2$

Substitute figures in the equation, we have:

$2*1.6*10^-^1^9 * 1800 = \frac{1}{2} * 6.64*10^-^2^7 * v'^2$

Solving for v' we have:

$v' = 41.65 * 10^4$

For electric field between plates, we use the formula :

$E = \frac{V}{d}$

Where V = 120

$E = \frac{120}{0.008}$

$15*10^3 N/C$

The magnitude of magnetic field, B, needed so that the alpha particles emerge undeflected will be given as:

$B = \frac{E}{v'}$

$B = \frac{15*10^3}{41.65*10^4}$

B = 0.036 T

Three people are pushing a 500 kg of box in the same direction. applied forces are 30 n, 20 n, and 10 n respectively. if the acc

GREYUIT [131]

The total force applied by the three people is:
$F=30 N+20 N+10 N=60 N$
This force is pushing toward the direction of the motion, while the frictional force $F_f$ points in the opposite direction.
We can write Newton's second law applied to the block: the resultant of the two forces must be equal to the product between the block's mass and its acceleration
$F-F_f = ma$
We know the mass of the block, m=500 kg, and the acceleration, $a=0.02 m/s^2$ , so we can find the friction:
$F_f = F-ma=60 N - (500 kg)(0.02 m/s^2)=50 N$
