4 0

The x-component of this vector inclined from the horizontal axis is  15m.

<h3>What is vector?</h3>

A vector is the representation of a physical quantity in magnitude and direction.

A vector incline at an angle in has two components. On in x direction and other is in y direction.

For the given length of vector = 45.6 m and the angle of inclination from the +x axis θ = 70.8°

The x component of the given vector is

= 45.6cos 70.8°

= 14.99 m

Thus, the x- component of this vector is 15m.

Answer:

(a) t = 1.67 s

(b) s₂ = 45 m

Explanation:

Here, we use the formula:

s = vt

FOR Seth:

s₁ = v₁t₁

where,

s₁ = distance covered by Seth

v₁ = speed of Seth = 9 m/s

t₁ = time taken by Seth

FOR Mack:

s₂ = v₂t₂

where,

s₂ = distance covered by Mack

v₂ = speed of Mack = 27 m/s

t₂ = time taken by Mack

since, initially Mack is 30 m behind Seth. Therefore,

(a)

s₂ = s₁ + 30 m

using formulae:

v₂t₂ = v₁t₁ + 30 m

but, the time of catching is same for both (t₁ = t₂ = t)

v₂t = v₁t + 30 m

using values:

(27 m/s)t - (9 m/s)t = 30 m

t = (30 m)/(18 m/s)

<u>t = 1.67 s</u>

(b)

s₂ = v₂t

using values:

s₂ = (27 m/s)(1.67 s)

<u>s₂ = 45 m</u>

What type of specialized cell in the eye is used for detecting low levels of light?
Hunter-Best [27]

Answer:

There are about six to seven million cones in a human eye and are most concentrated towards the macula. Cones are less sensitive to light than the rod cells in the retina (which support vision at low light levels), but allow the perception of color.

For a body to be in SHM, the restoring force must be __________ to displacement from equilibrium.
Ipatiy [6.2K]

Answer:

Proportional

Explanation:

The conditions that must be met to produce SHM are;

-The restoring force must be proportional to the displacement and act opposite to the direction of motion with no drag forces or friction.

- The frequency of oscillation does not depend on the amplitude.

Please help!How is constant or uniform acceleration used to explain free fall?
garik1379 [7]
Free fall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. For example, when a ball is thrown up in the air, the ball's velocity is initially upward.
