When will an object falling toward earth stop accelerating

Physics
2 answers:
aalyn [17]3 years ago

Answer:

Hope this helps!

Explanation:

As an object falls, it picks up speed. The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. At this instant in time, the net force is 0 Newton; the object will stop accelerating. An object falling toward earth stop accelerating when it velocity becomes terminal velocity. Or When weight becomes equal to Drag force acting on the object due to air resistance.

Answer:

percentage by volume of the solute = 45%

Explanation:

The percentage by volume of the solute in a solution is the percentage of the volume of the solute as against the overall volume of the solution.

In this example,

volume of solution = 300mL

volume of solute = 135mL

% volume of solute = (volume of solute ÷ volume of solution) × 100

= (135 ÷ 300) × 100

= 0.45 × 100 = 45%

∴ percentage by volume of the solute = 45%

Show your work and resoning for the below requirement.
Leno4ka [110]

Answer:

This value is less than the maximum tension of 500 lbs, making it safe for man to go to the tip flap

Explanation:

We must work on this problem using the rotational equilibrium equations and then they compared the tension values that the cable supports.

Let's start with fixing a reference system on the hinge of the flag, we take as positive the anti-clockwise turn

 They indicate the weight of the pole W₁ = 120 lb and a length of L = 9 ft, the weight of the man W₂ = 150, we assume that the cable is at the tip of the pole

            - T_{y} L + W₂ L + W₁ L / 2 = 0

            T_{y} = W₂ + W₁ / 2

            T_{y} = 120 + 150/2

            T_{y} = 195 lb

we use trigonometry to find the cable tension

             sin 30 = T_{y} / T

             T = T_{y} / sin 30

             T = 195 / sin 30

             T = 390 lb

This value is less than the maximum tension of 500 lbs, making it safe for man to go to the tip flap

             T < 500 lb

Oil of specific gravity 0.75 flows through a smooth contraction in a pipe at a volumetric flow rate of 3.2 cu ft / sec.Find the
pogonyaev

Answer:

The force required to hold the contraction in place is 665.91 N ↑

Explanation:

Given;

specific gravity of oil, γ = 0.75

Volumetric flow rate, V 3.2 Ft³/s = 0.0906 m³/s

\gamma =\frac{\rho_o}{\rho_w}

where;

\rho_o is the density of oil

\rho_w is the density of water = 1000 kg/m³

∴density of oil (\rho_o) = γ × density of water(\rho_w)

                               = 0.75 × 1000 kg/m³

                                = 750kg/m³

Buoyant Force = ρVg

                         = 750 × 0.0906 × 9.8

                         = 665.91 N ↑

This force acts upward or opposite gravitational force.

Therefore, the force required to hold the contraction in place is 665.91 N ↑

An insulated beaker with negligible mass contains liquid water with a mass of 0.240 kg and a temperature of 75.8°C . How much ic
sweet [91]

Answer:

Explanation:

Let mass of ice required is m kg

Heat gained by ice to attain zero degree

= m x 14.1 x 2100

= 29610m J

Heat gained by ice to melt = m x 3.34 x 10⁵ J

= 334000m J

Heat gained by water at zero degree to warm up to 27 degree

m x 4190 x 27 =113130 J

Total heat gained = 476740m J

Heat lost by hot water to cool up to 27 degree

.24 x 4190 x ( 75.8 - 27 )

= 49073.28 J

Heat lost = heat gained

476740 m = 49073.28

m = 49073.28/476740 kg

=102.93 gm
