3 0

For "A triangular plate with a non-uniform areal density has a mass M=0.500 kg...." the period of the oscillations.

T = 1.2042s

<h3>What is the period of the oscillations.?</h3>

The process of repeating variations of any quantity or measure about its equilibrium value in time is referred to as oscillation. Oscillation is defined as this process. Alternating between two values or revolving around a central value is another way to describe oscillation, which is a periodic fluctuation of a substance.

Generally, the equation for moment of inertia is mathematically given as

T = 2 π √( I / mgd )

Therefore, a moment of inertia

I = 9.00×10-3 + md^2 ;

I=9.00*10^{-3}+ 0.5 * 0.3^2

I=0.054

T = 2π $\sqrt{( 0.054 / (0.5 *9.8 * 0.3 )}$

T = 1.2042s

In conclusion, the period of the oscillations.

T = 1.2042s

How long does it take light from a camera to travel to the face of someone standing 7 meters away?

mestny [16]

The time taken for the light to travel from the camera to someone standing 7 m away is 2.33×10¯⁸ s

Speed is simply defined as the distance travelled per unit time. Mathematically, it is expressed as:

<h3>Speed = distance / time </h3>

With the above formula, we can obtain the time taken for the light to travel from the camera to someone standing 7 m away. This can be obtained as follow:

Distance = 7 m

Speed of light = 3×10⁸ m/s

Time = Distance / speed

Time = 7 / 3×10⁸

Therefore, the time taken for the light to travel from the camera to someone standing 7 m away is 2.33×10¯⁸ s

A businesswoman is rushing out of a hotel through a revolving door with a force of 80 N applied at the edge of the 3 m wide door

mel-nik [20]

Answer:

Explanation:

Given

Force applied $F=80\ N$

Door is $d=3\ m$ wide

for gate to revolve Properly Pivot Point must be at center i.e. 1.5 from either end

Torque applied is $T=force\times distance$

Maximum torque

$T_{max}=F\times \frac{d}{2}$

$T_{max}=80\times \frac{3}{2}$

$T_{max}=120\ N-m$

Dan is gliding on his skateboard at 4.00m/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at 6

frozen [14]

To solve this problem we will apply the concepts related to the conservation of the Momentum. For this purpose we will define the momentum as the product between mass and velocity, and by conservation the initial momentum will be equal to the final momentum. Mathematically this is,

$m_1u_1+m_2u_2 = m_1v_1+m_2v_2$
