Answer:
-107 m
Explanation:
Sum of forces in the y direction:
∑F = ma
-qE = ma
a = -qE/m
a = -(1.60×10⁻¹⁹ C) (304 N/C) / (9.11×10⁻³¹ kg)
a = -53.4×10¹² m/s²
Given in the y direction:
v₀ = 0 m/s
a = -53.4×10¹² m/s²
t = 2×10⁻⁶ s
Find: Δy
Δy = v₀ t + ½ at²
Δy = (0 m/s) (2×10⁻⁶ s) + ½ (-53.4×10¹² m/s²) (2×10⁻⁶ s)²
Δy = -107 m

Displacement of a body is always in a straight line in the direction of the final position regardless of the path taken to reach the final position.
Therefore, the displacement of the car can be obtained by joining the car's initial position to the final position and then counting the number of squares covered by the line. Then we multiply the number of squares by the scale and note the direction of the final position from the initial.
that is: 4×1km= 4km North since displacement is a vector.
A machine that provides both constant speed and maximum resistance throughout the full range of motion provides an isokinetic type of muscular contraction. This type of contraction occurs when the muscle would contract and shorten at a consistent and constant speed. To have this contraction, special equipment are to be used. An example of an equipment would be an <span>Isokinetic Dynamometer. </span>However, this type of training is said to be one of the fastest in increasing the muscle strength and the muscle endurance. With this training, the muscles being targeted would gain strength consistently and evenly throughout the whole duration of exercise.
Steel is the correct answer because steel when on being applied heat will either change its state that too after hours because of its melting point being high or remain in that position only whereas wood turns into ashes...that is why we use metal utensils in the kitchen
