A spring-loaded toy gun is used to shoot a ball of mass 1.5 kg straight up in the air, as shown. The spring has spring constant

asambeis [7]

Answer:

Part a)

U = 15.5 J

Part b)

h = 1.05 m

Part c)

v = 4.55 m/s

Explanation:

Part a)

Initial potential energy stored in the spring is given by

$U = \frac{1}{2}kx^2$

now we have

$k = 777 N/m$

x = 20.0 cm

now from above formula we will have

$U = \frac{1}{2}(777)(0.20)^2$

$U = 15.5 J$

Part b)

By mechanical energy conservation law we can say that initial spring potential energy stored = final gravitational potential energy at the top position

$\frac{1}{2}kx^2 = mgh$

$15.5 = 1.5(9.8)h$

$h = 1.05 m$

So maximum height from gun is 1.05 m

Part c)

For muzzle velocity of the ball we can use the energy conservation again

According to which the final kinetic energy of the ball = initial spring energy stored in it

$\frac{1}{2}mv^2 = \frac{1}{2}kx^2$

$(\frac{1}{2})(1.5 v^2) = 15.5$

$v = v = 4.55 m/s$

A negative charge of -3.0 x 10^-5 C is placed 0.35 m from a positive charge of 9.0 x 10^-5 C. What is the force between the two

Ilia_Sergeevich [38]

Answer:

the force between the two charges is 198.37 N

Explanation:

Given;

charge of the first particle, Q₁ = -3 x 10⁻⁵ C

charge of the second particle, Q₂ = 9.0 x 10⁻⁵ C

distance between the two charges, r = 0.35 m

The force between the two charges is calculated from Coulomb's law;

$F = \frac{kQ_1Q_2}{r^2}$

where k is Coulomb's constant = 9 x 10⁹ Nm²/C²

$F = \frac{(9\times 10^9)(3.0\times 10^{-5})(9\times10^{-5} )}{0.35^2} \\\\F = 198.37 \ N$

Therefore, the force between the two charges is 198.37 N

Finally, the switch on the electromagnet is reopened. The magnitude of the external magnetic flux through the wire loop ______ (

zubka84 [21]

Answer:

Decreases ,,clockwise

Explanation:

When the switch is reopened then magnitude of magnetic flux through the loop will decreases and the direction of induced current will be clockwise (when seen from clockwise.

So the answer of the fill in the blank is decreases and clockwise.

Answer - B and B.

B) Decreases ,B)clockwise
