Answer:
62 N
Explanation:
Sum of the forces on the toolbox:
∑F = ma
T − mg = ma
T = mg + ma
T = m (g + a)
T = (5.0 kg) (9.8 m/s² + 2.5 m/s²)
T = 61.5 N
Rounded to two significant figures, the force exerted by the rope is 62 N.

Answer:
E₂ / E₁ = 521.64 / 5.95 =87.67
Explanation:
Let d be the distance covered inside electric field . Lt q be the magnitude of charge.
Force under field E₁ = q E₁
acceleration = qE₁/ m
d = 1/2 a t²
d = .5 ( qE₁ / m) x 32.3²
d = 521.64 ( qE₁ / m)
Similarly for return journey,
d = .5 x ( qE₂ / m) x 3.45²
d = 5.95x( qE₂ / m)
521.64 ( qE₁ / m) = 5.95x( qE₂ / m)
E₂ / E₁ = 521.64 / 5.95 =87.67
Answer: Two men who helped in the development of psychology in Germany was Wilhelm Wundt, and in United States was William James.
Explanation:
Wilhelm Wundt was a German scientist, who was the first person who introduced psychology. He studied the conscious experience as a part of scientific study. It emphasis the identification of the components of the consciousness. Introspection is the process through which conscious experiences can be analyzed.
William James was a scientist, native of U.S. His purpose was to study the function of behavior all over the world. This perspective was known as functionalism. This emphasizes over the fact that how mental activities helps how organisms fit into its surrounding environment.
