Answer:

No

Explanation:

If the coil is accelerated parallel to the magnetic field, it means also that the force on the coil acts parallel to the field. For current to be induced in a coil, a basic condition must be met which is that the directions of force (acceleration) and the magnetic field must be perpendicular to each other. This brings about current being induced in a direction perpendicular to bothering the directions of the force acting on the coil and the that of the magnetic field. This current would flow through the coil in either a clockwise or anticlockwise manner.

Since the coil is accelerated parallel to the magnetic field, no current is induced in it.

Erica (37kg ) and Danny (49kg ) are bouncing on a trampoline. Just as Erica reaches the high point of her bounce, Danny is movin
Semmy [17]

Answer:

2.45 m/s

Explanation:

From the law of conservation of momentum,

The total momentum before the grab = Total momentum after the grab.

mu+m'u' = V(m+m')................... Equation 1

Where m = mass of Erica, m' = mass of Danny, u = initial velocity of Erica, u' = initial velocity of Danny, V = common velocity after garb

Make V the subject of the equation

V = (mu+m'u')/(m+m')............. Equation 2

Given: m = 37 kg, m' = 49 kg, u = 0 m/s(at the maximum height), u' = 4.3 m/s

Substitute into equation 2

V = (37×0+49×4.3)/(37+49)

V = 210.7/86

V = 2.45 m/s

Hence their speed just after the grab = 2.45 m/s

What are the reactants
xenn [34]

Answer:

Reactants are initiators of a chemical reaction

Explanation:

In a chemical reaction, there are two types of substances involved: reactants and products.

The reactants are substances that are utilized to in a chemical reaction which undergo certain changes and thereby producing products at the end of a reaction

On can write chemical equation as :

A + B → AB

where A and B are reactants which underwent a reaction to produce the product AB.

For example

2H_{2} + O_{2} → 2H_{2}O

|______|        ↓

Reactants      Products

When writing a chemical equation, reactants are always written on left hand side of an arrow and the products on the right hand side.

What is the wavelength associated with 0.113kg ball traveling with velocity of 43 m/s?
ollegr [7]

Answer:

Wavelength = 1.36 * 10^{-34} meters

Explanation:

Given the following data;

Mass = 0.113 kg

Velocity = 43 m/s

To find the wavelength, we would use the De Broglie's wave equation.

Mathematically, it is given by the formula;

Wavelength = \frac {h}{mv}

Where;

h represents Planck’s constant.

m represents the mass of the particle.

v represents the velocity of the particle.

We know that Planck’s constant = 6.6262 * 10^{-34} Js

Substituting into the formula, we have;

Wavelength = \frac {6.6262 * 10^{-34}}{0.113*43}

Wavelength = \frac {6.6262 * 10^{-34}}{4.859}

Wavelength = 1.36 * 10^{-34} meters
