Explanation:

Given that,

Length of the building, l = 631 m

Breadth of the building, b = 707 yards

Height of the building, h = 110 ft

1 meter = 3.28084 feet

631 m = 2070.21 feet

1 yard= 3 feet

707 yards = 2121 feet

(a) The volume of any cuboidal shape is given by :

V=l\times b\times h

V=2070.21\ ft\times 2121\ ft\times 110\ ft

V=4.83\times 10^8\ ft^3

(b) V=4.83\times 10^8\ ft^3

V=(4.83\times 10^8\ ft^3)(\dfrac{1\ m}{3.281\ ft})^3

V=1.37\times 10^7\ m^3

Hence, this is the required solution.

On an amusement park ride, passengers are seated in a horizontal circle of radius 7.5 m. The seats begin from rest and are unifo
timofeeve [1]

Answer:

a = 0.5 m/s²

Explanation:

Applying the definition of angular acceleration, as the rate of change of the angular acceleration, and as the seats begin from rest, we can get the value of the angular acceleration, as follows:

ωf = ω₀ + α*t

⇒ ωf = α*t ⇒ α = \frac{wf}{t} = \frac{1.4 rad/s}{21 s} = 0.067 rad/s2

The angular velocity, and the linear speed, are related by the following expression:

v = ω*r

Applying the definition of linear acceleration (tangential acceleration in this case) and angular acceleration, we can find a similar relationship between the tangential and angular acceleration, as follows:

a = α*r⇒ a = 0.067 rad/sec²*7.5 m = 0.5 m/s²

The minute hand of a wall clock measures 16 cm from its tip to the axis about which it rotates. The magnitude and angle of the d
olya-2409 [2.1K]

Answer:

Explanation:

Given

Minute hand length =16 cm

Time at a quarter after the hour to half past i.e. 1 hr 45 min

Angle covered by minute hand in 1 hr is 360 and in 45 minutes 270

|r|=\frac{3\times 2\pi r}{4}=75.408 cm

Angle =270^{\circ}

(c)For the next half hour

Effectively it has covered 2 revolution and a quarter

|r|=\frac{2\pi r}{4}=25.136 cm

angle turned =90^{\circ}

(f)Hour after that

After an hour it again comes back to its original position thus displacement is same =25.136

Angle turned will also be same i.e. 90 ^{\circ}

NeX [460]

The correct answer are

a)  "The number of muscle fibers best determines how powerful a muscle will be"

b) "The more a muscle shortens, the more power it generates."

Reason :

Muscle fiber in longitudinal directions generate more power

Multipennate muscles do not produce much power because the tendon branches within muscle .

julsineya [31]

Answer:

J = 0.693 N.s

Explanation:

The impulse of one single drop is given by:

J1 = m*(Vf - Vo)   where Vf = 0

J1 = -9.25*10^{-4}N.s

The magnitude of the total impulse will be:

Jt = J1 * 150 * 5

Jt = 0.693 N.s
