An apple has a density of 641 kg/m3. Water has a

Physics
1 answer:
Vlad [161]3 years ago

Answer:

D

Explanation:

Since the apple is 641kg/m3 and water is 1000kg/m3 then the apple will float. Light materials float on top of the water similar to how oil is always on top of the water layer. Since the two are close so the apple will partially float

Suzie skydiver, who weighs 500 n, reaches terminal velocity of 90 km/h. the air resistance on suzie is then
masha68 [24]
<span>Weight of the skydiver m = 500 N
 Terminal velocity V = 90 km/h
 Here the weight of the person acts as the force, so based on the Newton's third law the applied is the force what we but in the opposite direction making the resistance. So the air resistance exerted on Suzie will be her weight that is 500N</span>

An object of mass 1.0 kg is at rest on a smooth inclined plane with height h, length 8 m,
TEA [102]

The coefficient of kinetic friction for the rough horizontal surface is 0.66.

The given parameters;

  • <em>mass of the object, m = 1 kg</em>
  • <em>length of the inclined plane, L = 8 m</em>
  • <em>angle of inclination of the plane, θ = 30⁰ </em>
  • <em>distance traveled before hitting the spring, d₁ = 4 m</em>
  • <em>distance traveled after hitting the spring, d₂ = 1.3 m</em>
  • <em>the spring constant, k = 26.5 N/m</em>

Apply work-energy theorem; the work done the force of friction is equal to the energy stored in the spring.

F_kd_1 = \frac{1}{2} kd_2^2\\\\\mu_kmg cos(\theta)d_1 = \frac{1}{2} kd_2^2\\\\\mu_k(1 \times 9.8 \times cos(30)\times 4) = \frac{1}{2} \times 26.5 \times (1.3)^2\\\\33.95\mu_k = 22.39\\\\\mu_k = \frac{22.39}{33.95} \\\\\mu_k = 0.66

Thus, the coefficient of kinetic friction for the rough horizontal surface is 0.66.
