Answer:

The magnitude of the electric field is $5.1 \times 10^{11} \frac{N}{C}$

Explanation:

Given:

Charge of electron $q = 1.6 \times 10^{-19}$ C

Separation between two charges $r = 5.3 \times 10^{-11}$ m

For finding the magnitude of the electric field,

$E= \frac{kq}{r^{2} }$

Where $k = 9 \times 10^{9}$

$E = \frac{9 \times 10^{9} \times 1.6 \times 10^{-19} }{(5.3 \times 10^{-11} )^{2} }$

$E = 5.1 \times 10^{11}$ $\frac{N}{C}$

Therefore, the magnitude of the electric field is $5.1 \times 10^{11} \frac{N}{C}$

Which type of plate boundary or zone would be most likely to lead to above-ground volcanic activity?

Anna007 [38]

Answer:

Convergent plate boundary

Explanation:

The convergent plate boundary refers to the type of boundary where two plates move towards each other. Due to this type of motion, there forms a subduction zone, where the denser plate subducts below the lighter plate. This zone of subduction is commonly identified by the presence of a deep and narrow V-shaped depression which is commonly known as the oceanic trench.

When the subducting plate enters into the region of the asthenosphere, the rocks melt and mix with the magma. This magma is then pushed upward due to the force exerted by the convection current that forms in the mantle, and further reaches the over-riding plate and eventually give rise to the formation of volcanoes and volcanic/island arcs.

Thus, this type of plate boundary is responsible for the formation of above-ground volcanic activities.

A student stretches a spring, attaches a 1.20 kg mass to it, and releases the mass from rest on a frictionless surface. The resu

Sphinxa [80]

Answer:

the speed of the mass when it is halfway to the equilibrium position is 1.26 m/s

Explanation:

Given that;

mass of the object m = 1.20 kg

period of oscillation = 0.750 s

Amplitude ( A/x) = 15.0 cm = 0.15 m

now;

a) Determine the oscillation frequency;

oscillation frequency f = 1/T

we substitute

f = 1 / 0.750 s

f = 1.33 Hz

Therefore, the oscillation frequency is 1.33 Hz

b) Determine the spring constant;

we solve for spring constant from the following expression;

T = 2π√(m/k)

k = 4π²m / T²

so we substitute

k = (4π² × 1.20) / (0.750)²

k = 47.3741 / 0.5625

k = 84.22 N/m

Therefore, the spring constant is 84.22 N/m

c) determine the speed of the mass when it is halfway to the equilibrium position

So, at equilibrium, the energy is equal to K.E

such that;

1/2mv² = 1/2kx²

mv² = kx²

v² = kx² / m

v = √( kx²/m)

we substitute

v = √( 84.22×(0.15 m)²/ 1.2 )

v = √( 1.89495 / 1.2 )

v = √ 1.579125

v = 1.26 m/s

Therefore, the speed of the mass when it is halfway to the equilibrium position is 1.26 m/s

Apart from height above ground, what does the amount of gravitational potential energy that an object has on earth depend on?

damaskus [11]

Answer:

Gravitational potential energy is due to the position of an object above Earth's surface. The object has the potential to fall due to gravity.

Explanation:

Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). hope this helps you :)
