1 answer:
Ray Of Light [21]3 years ago
4 0

Answer:

5 m/s

Explanation:

Assuming no air resistance, the horizontal acceleration is 0 m/s².  So the final velocity is the same as the initial velocity.

A rider on a bike with the combined mass of 100kgattains aterminal speed of 15m/son a 12% slope. Assuming that the only forces a
Semmy [17]

Answer:

C_d = 0.942

Explanation:

Let's first calculate the angle of inclination.

Formula is;

tan θ = (%slope)

% Slope is given as 12%

Thus;

θ = tan^(-1) (12/100)

θ = 6.843°

Let's now calculate the force due to the weight of the rider and bike combined from;

F = mg sin θ

We are given; m = 100 kg.

Thus;

F = 100 × 9.81 × sin 6.843

F = 116.885 N

The drag force will also be the same as the force due to the weight of the body. Thus;

Drag force; F = C_d(½ρu²A)

Where;

C_d is drag coefficient

ρ is density

U is terminal speed

A is area

We are given;

A = 0.9 m²

U = 15 m/s

From online tables, density of air is approximately 1.225 kg/m³

Thus;

116.885 = C_d(½ × 1.225 × 15² × 0.9)

116.885 = 124.03125C_d

C_d = 116.885/124.03125

C_d = 0.942

olga nikolaevna [1]

Answer:

A. China rose

B. Methyl red

C. Phenolphthalein

Explanation:

An indicator is a substance used to detect the presence of an acid or base as characterized by the indicators color change. An indicator can either be natural or synthetic depending on whether it is obtained from naturally occurring substance (natural) or synthesized in a laboratory (synthetic).

A. China rose is a type of natural indicator that turns deep PINK or MAGENTA in the presence of an acid or GREEN in the presence of a base.

B. Methyl red is a synthetic Indicator that turns RED in the presence of an acid or YELLOW in the presence of a base.

C. Phenolphthalein is an organic dye that is originally colorless but turns PINK in the presence of a base but remains colorless in the presence of an acid or neutral substance.

When a ray is incident upon a plane mirror as shown in the diagram, what is the angle of refraction?
Anna11 [10]

Answer:

0 degrees

Explanation:

this is because when the light ray hits a surface a medium at 90 degrees then the angle of incidence = 0 , thus light doesn't bend when it enters the medium, no bending means angle of refraction is 0 degrees

hope this helps ,please mark it
