Can at transform plate boundaries, two plate move toward each other true or false

A small sphere with a mass of 441 g is moving upward along the vertical +y-axis when it encounters an electric field of 5.00 N/C

sweet-ann [11.9K]

In your question where the ask is to calculate the charge that the small sphere carries which is the mass of it is 441g moving at an acceleration of 13m/s^2 nad having and electric field of 5N/C. So the formula in getting the charge is mutliply the mass and the quotients of Acceleration and the Electric Field so the answer is 1,146.6

An unbanked (flat) curve of radius 150 m is rated for a maximum speed of 32.5 m/s. At what maximum speed, in m/s, should a flat

Rasek [7]

Answer:

The maximum speed is 21.39 m/s.

Explanation:

Given;

radius of the flat curve, r₁ = 150 m

maximum speed, $v_{max}$ = 32.5 m/s

The maximum acceleration on the unbanked curve is calculated as;

$a_c_{max} = \frac{V_{max}^2}{r} \\\\a_c_{max} = \frac{32.5^2}{150} \\\\a_c_{max} = 7.04 \ m/s^2$

the radius of the second flat curve, r₂ = 65.0 m

the maximum speed this unbanked curve should be rated is calculated as;

$a_c_{max} = \frac{V_{max}^2}{r_2} \\\\V_{max}^2 = a_c_{max} \ \times \ r_2\\\\V_{max} = \sqrt{a_c_{max} \ \times \ r_2} \\\\V_{max} =\sqrt{7.04 \ \times \ 65} \\\\V_{max} = 21.39 \ m/s$

Therefore, the maximum speed is 21.39 m/s.

3. 3.0*1015 electrons are removed from one side of a parallel plate capacitor and travel to the other side of the capacitor. You

natima [27]

Answer:

True

$Q = 480 \mu C$

Explanation:

As we know that total charge is always quantized and in the terms of multiples of charge of single electron

so we have

Q = Ne

here we know that

$N = 3.0 \times 10^{15}$

also we know that

$e = 1.6 \times 10^{-19} C$

so we have

$Q = (3.0 \times 10^{15})(1.6 \times 10^{-19} C)$

$Q = 480 \mu C$

Since this charge is in multiple of micro coulomb units so yes it is possible to measure it

and the magnitude of this charge is given as

$Q = 480\mu C$

In what two ways is heat transmitted by a conductor

Advocard [28]

Heat can be transmitted by a conductor using conduction and convection method.

<u>Explanation:</u>

Heat energy can be transferred in three ways. In other words, the propagation of heat energy can be done by conduction, convection and radiation. Among these three conduction and convection requires a conducting medium, while radiation does not require any medium for transmitting the heat energy.

Conduction is the form of heat energy transfer where the energy is transmitted through the medium in contact with each other. So the electrons will collide with each other and the medium should be in contact and they should be highly conducting in nature, to perform conduction.

In case of convection, the liquid or gas molecules transfer the thermal energy from one point to another. No contact between the medium is required. It passes through the flow of gas or liquids. Thus, conduction and convection are the two methods by which heat can be transmitted by a conductor.
