Please help! Urgent!!! My teacher wants us to make something about energy. For instance define Kinetic energy. Then we need to b

uild something that represents it. In a past time I did volume and used a graduated cyclometer that I filled up with water and froze. This unit is energy, so anything that has to do with energy. Please give me a few ideas on what I can do as well as where I can find the supplies! Before the weekend (first weekend in march) urgent! Best idea will get brainest and a thanks!!!

Scientists in the laboratory create a uniform electric field e⃗ = 6. 0×105 k^v/m in a region of space where b⃗ =0⃗
zvonat [6]

Scientist in the laboratory create uniform electric field.

PART A: The electric field in rocket frame is  (0,0,  6.0 × 10 ⁵).

PART B: The magnetic field in the rocket frame is  7.3 × 10⁻⁶ j∧  .

<h3>What is uniform electric field?</h3>

The electric field whose strength is not changing with respect to time is called uniform magnetic field.

The electric field is 6.0 × 10 ⁵ k^v/m and the magnetic field is zero.

E' = E + (V×B)

    = 6.0 × 10 ⁵ + (1.1 × 10⁶ × 0)

E' = 6.0 × 10 ⁵ k∧

(Ex , Ey, Ez) = (0,0,  6.0 × 10 ⁵)

The new magnetic field is represented as

B' = B - 1 /c²(v × E)

   =0 - 1 / (3× 10⁸)²(1.1 × 10⁶ i∧ × 6.0 × 10 ⁵k∧ )

B' = 7.3 × 10⁻⁶ j∧

PART A: The electric field in rocket frame is  (0,0,  6.0 × 10 ⁵).

PART B: The magnetic field in the rocket frame is 7.3 × 10⁻⁶ j∧ .
