Answer:

B. less

Explanation:

acceleration due to gravity on Earth, g = 9.8 m/s²

acceleration due to gravity on Moon, g = 1.6 m/s²

Given mass of the object as, m = 5 kg

Weight of an object is given as, W = mg

Weight of the object on Earth, W = 5 x 9.8 = 49 N

Weight of the object on Moon, W = 5 x 1.6 = 8 N

Therefore, the object weighs less on the moon compared to its weight on Earth.

The correct option is "B. less"

A dipole is located at the origin, with charges +3 nC and -3 nCseparated by 4 μm. Consider a spherical Gaussian surfacecentered

kirza4 [7]

Answer:

Explanation:

a )

The Gaussian surface must have contained both the charges like +3 nC and - 3 nC , total charges being zero . According the Gauss's law , total electric flux over a closed surface is equal to 1 / ε₀ times the total charge contained inside the closed surface .

Since total charge inside is zero , total flux will be 1 / ε₀ x 0 = 0

b )

In this case the Gaussian surface is so small that it contains only the charge

+ 3 nC .

So electric flux over the Gaussian surface

= ( 1 / ε₀ ) x 3 x 10⁻⁹

= (1 / 8.85 x 10⁻¹² ) x 3 x 10⁻⁹

= 3 x 10³ / 8.85

= 339 weber.

1. A surfer moving with an initial speed of 1.5 m/s catches a wave and accelerates at a constant

Vikki [24]

Answer:

a) Δx ≈ 8.4 m

b) v ≈ 6.1 m/s

Explanation:

Given:

v₀ = 1.5 m/s

a = 2.1 m/s²

t = 2.2 s

a) Find: Δx

Δx = v₀ t + ½ at²

Δx = (1.5 m/s) (2.2 s) + ½ (2.1 m/s²) (2.2 s)²

Δx ≈ 8.4 m

b) Find: v

v = at + v₀

v = (2.1 m/s²) (2.2 s) + (1.5 m/s)

v ≈ 6.1 m/s

A 10-N force is needed to move an object with a constant velocity of 5.0 m/s. What power must be delivered to the object by the

vagabundo [1.1K]

The power that must be delivered to the object by the force is 50 W

Power is defined as the rate of doing work. The power of an object in relation to the force and velocity is given by the following equation:

Power (P) = Force (F) × velocity (v)

P = F × v

From the question given above, the following data were obtained:

Force (F) = 10 N
Velocity (v) = 5 m/s
Power (P) =?

P = F × v

P = 10 × 5

Thus, the power that must be delivered to the object by the force is 50 W
