Diceplacement is the distance an object has traveled in a certain direction
for example, if you were to walk North for 20m, then east for 40m, the <u>distance</u> you have traveled is 60m however your displacement is the distance between your starting position and your end position;
sqrt(20^2+40^2) = 44.7m
and because displacement is a vector, there needs to be a direction;
sin(theta)=40/44.7
theta=63.4 degrees East of North

therefore the true displacement is 44.7m at 63.4 degrees East of North

A 1300-turn coil of wire that is 2.4cm in diameter is in a magnetic field that drops from 0.15T to 0 T in 12ms . The axis of the

krek1111 [17]

The emf induced in the coil at the given magnetic field strength is 4.53 V.

<h3>what is mangetic field?</h3>

magnetic field is a type of field where all things use for magnesium.

The given parameters;

number of turns, N = 1300 turns

diameter of the coil, d = 2.2 cm

initial magnetic field, B₁ = 0.11 T

final magnetic field, B₂ 0

time, t = 12 ms

The area of the coil is calculated as follows;

The emf induced in the coil is calculated as follows;l

Thus, the emf induced in the coil at the given magnetic field strength is 4.53 V.

I’m like kinda bad at physics so ya please help

uysha [10]

Answer:

99 joules.

Explanation:

Let m denotes mass of the object and v denotes velocity.

If mass has units of kilograms and the velocity has units of meters per second then the kinetic energy has units of joules.

Kinetic energy is an energy possessed by a body in motion.

Mass (m) = 99 kg

Velocity (v) = 2 m/s

To find kinetic energy, use the following formula:

Kinetic energy = $\frac{1}{2}mv^2=\frac{1}{2}(99)(2)=99$ joules
