Answer:

\boxed{Force \: on \: body = 60 \: N}

Given:

Mass of body = 20 kg

Acceleration = 3 m/s²

Explanation:

Force = mass × acceleration

= 20 × 3

= 60 kg m/s² or 60 N

<em>Hey</em><em>!</em><em>!</em>

<em>Sol</em><em>ution</em><em>,</em>

<em>Mass</em><em>(</em><em>m</em><em>)</em><em>=</em><em>2</em><em>0</em><em>k</em><em>g</em>

<em>Accele</em><em>ration</em><em> </em><em>due</em><em> </em><em>to</em><em> </em><em>gravity</em><em>(</em><em>g</em><em>)</em><em>=</em><em>3</em><em> </em><em>m</em><em>/</em><em>s^</em><em>2</em>

<em>Force</em><em>=</em><em>?</em>

<em>Now</em><em>,</em>

<em>Force</em><em>=</em><em>m</em><em>*</em><em>g</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em> </em><em>2</em><em>0</em><em>*</em><em>3</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em> </em><em>6</em><em>0</em><em> </em><em>Newton</em>

<em>The</em><em> </em><em>force</em><em> </em><em>is</em><em> </em><em>6</em><em>0</em><em> </em><em>Newton</em><em> </em>

<em>Hope </em><em>it</em><em> </em><em>helps</em>

<em>Good</em><em> </em><em>luck</em><em> on</em><em> your</em><em> assignment</em><em>.</em><em>.</em>

A plane drops a hamper of medical supplies from a height of 5000 m during a practice run over the ocean. The plane’s horizontal
Marizza181 [45]

Answer:

346.70015 m/s

Explanation:

In the x axis speed is

v_x=149\ m/s

In the y axis

v_y=\sqrt{2gh}\\\Rightarrow v_y=\sqrt{2\times 9.8\times 5000}

The resultant velocity is given by

v=\sqrt{v_x^2+v_y^2}\\\Rightarrow v=\sqrt{149^2+2\times 9.8\times 5000}\\\Rightarrow v=346.70015\ m/s

The magnitude of the overall velocity of the hamper at the instant it strikes the surface of the ocean is 346.70015 m/s

musickatia [10]

Answer:

(C) greater than zero but less than 45° above the horizontal

Explanation:

The range of a projectile is given by R = v²sin2θ/g.

For maximum range, sin2θ = 1 ⇒ 2θ = sin⁻¹(1) = 90°

2θ = 90°

θ = 90°/2 = 45°

So the maximum horizontal distance R is in the range 0 < θ < 45°, if θ is the angle above the horizontal.

Playing a certain musical note on a trumpet
Virty [35]

Answer:

(1) Resonance

Explanation:

Resonance is the process whereby a system is set into vibration due to the vibration of a nearby system with larger amplitude. The frequency at which this vibration takes place is called the resonant frequency.

It is a phenomenon of amplification that occurs when the frequency of a periodically applied force is in harmonic proportion to the natural frequency of the system on which it acts.
