A company designed and sells an ultrasonic​ receiver, which detects sounds unable to be heard by the human ear. The receiver can

detect mechanical and electrical sounds such as leaking​ gases, air,​ corona, and motor friction noises. It can also be used to hear​ bats, insects, and even beading water. The receiver is 1818 in. deep. The focus is 6 in.6 in. from the vertex. Find the diameter of the outside edge of the receiver.

The diameter at the outer edge of the receiver is derived from the given parameters within the schematic free body diagram. Here, point A indicates the vertex where the receiver is situated, S is designated as the focus, BP denotes the radius of the outer edge, and BC is twice the radius (the diameter). With AS as 4 inches and AP as 18 inches, and by utilizing the corresponding parabolic equation, the resulting diameter BC is calculated as 2r.

A reactant is any substance that takes part in a chemical reaction. Conversely, a product is what emerges from the chemical transformation. A familiar example of a chemical change is rust formation. In this reaction, oxygen and iron, which serve as the reactants, react to produce a substance known as iron oxide, or rust.

Determine the torque applied to the shaft of a car that transmits 225 hp
Keith_Richards [2911]

Incomplete query. The complete inquiry is as follows

Calculate the torque exerted on the shaft of a vehicle transmitting 225 hp at a rotation speed of 3000 rpm.

Response:

Torque=0.51 Btu

Analysis:

Given Information

Power=225 hp

Revolutions =3000 rpm

To determine

T( torque )=?

Process

As an object is moved by force over a distance, work is performed on that object. Similarly, when torque rotates an object through an angle, work is also accomplished.

T(Torque)=\frac{W(Work)}{2\pi n(Revolutions) }

kicyunya [2911]
The formula used is known as the Law of Universal Gravitation. The gravitational constant G is 6.67×10⁻¹¹ Nm²/kg². The Earth's mass is <span>5.972 ×10</span>²⁴ kg. The mass of the rocket is negligible in comparison to Earth’s mass, hence it is unnecessary for our calculations. Plugging in the values:

F = (6.67×10⁻¹¹ Nm²/kg²)(5.972 ×10²⁴ kg)/(4000 miles*(1.609 km/1 mile))²
F = 9616423.08 N

The work done is given by
W = Fd
W = (9616423.08 N)(2000 miles*1.609 km/mile)
W = 9.095×10¹⁰ Joules

A mass attached to a 66.4 cm long string starts from rest and is rotated 36.6 rev in1 min before reaching a final angular speed.
Ostrovityanka [2827]

Answer:

0.128 rad/s², 7.66 rad/s

Explanation:

length, l = 66.4 cm

initial angular velocity, ωo = 0 rad/s

Let ω represent the final angular velocity.

Let α denote the angular acceleration.

number of revolutions, n = 36.6

time taken, t = 1 min = 60 seconds

Angle rotated, θ = 2πn = 2 x 3.14 x 36.6 = 229.85 rad

Apply the second equation of motion for angular dynamics

\theta =\omega _{0}t+\frac{1}{2}\alpha t^{2}

229.85 = 0 + 0.5 x α x 60 x 60

α = 0.128 rad/s²

Utilize the first equation of motion

ω = ωo + αt

ω = 0 + 0.128 x 60

ω = 7.66 rad/s
