Answer:

As Per Provided Information

  • Velocity of projection u is 25m/s
  • Angle made by ball ∅ is 50°

We have been asked to determine the maximum height reached by the object .

here we will take acceleration due to gravity g is 9.8 m/s².

For calculating the maximum height attained by the object we will use the following formula .

\boxed{\bf \:H_{(max)} \:  =  \cfrac{u {}^{2}  {sin}^{2} \theta }{2g}}

Substituting all the value in above equation we obtain

\sf \qquad \: \longrightarrow\:H_{(max)} \:  =  \cfrac{ {25}^{2} {sin}^{2} {50}^{ \circ}   }{2 \times 9.8}  \\  \\  \\ \sf \qquad \: \longrightarrow\:H_{(max)} =  \cfrac{625 \times(0.766) {}^{2}  }{19.6}  \\  \\  \\ \sf \qquad \: \longrightarrow\:H_{(max)} =  \cfrac{625 \times 0.586756}{19.6}  \\  \\  \\ \sf \qquad \: \longrightarrow\:H_{(max)} =  \cfrac{366.7225}{19.6}  \\  \\  \\ \sf \qquad \: \longrightarrow\:H_{(max)} =  \cancel \cfrac{366.7225}{19.6}  \\  \\  \\ \sf \qquad \: \longrightarrow\:H_{(max)} =18.71 \: m

<u>Therefore</u><u>,</u>

  • <u>Maximum</u><u> height</u><u> </u><u>reached</u><u> by</u><u> </u><u>the </u><u>object</u><u> </u><u>is </u><u>1</u><u>8</u><u>.</u><u>7</u><u>1</u><u> </u><u> </u><u>meters</u><u>.</u>

What is the difference between resilience and modulus of resilience
pshichka [43]
<span>Resilience is the amount of energy that can be put into a volume of material and still be stored elastically. ie When the energy goes away, the material regains its undeformed shape. The Mod of R is the amount that can be stored by a unit volume of that material. The Mod of R is heavily related to Youngs Modulus.</span>

A rock is thrown downward from an unknown height above the ground with an initial speed of 6.1 m/s. It strikes the ground 1.7 s
insens350 [35]

Answer:

24.531 m

Explanation:

t = Time taken = 1.7 s

u = Initial velocity = 6.1 m/s

v = Final velocity

s = Displacement

g = Acceleration due to gravity = 9.81 m/s² = a

Equation of motion

s=ut+\dfrac{1}{2}at^2\\\Rightarrow s=6.1\times 1.7+\dfrac{1}{2}\times 9.8\times 1.7^2\\\Rightarrow s=24.531\ m

The initial height of the rock above the ground is 24.531 m

Studying this brochure from nasa, which explains more detail the instruments carried by the Juno spacecraft which scientific act
adoni [48]

Answer:

Juno scientific payload includes:

  • A gravity/radio science system (Gravity Science)
  • A six-wavelength microwave radiometer for atmospheric sounding and composition (MWR)
  • A vector magnetometer (MAG)
  • Plasma and energetic particle detectors (JADE and JEDI)
  • A radio/plasma wave experiment (Waves)
  • An ultraviolet imager/spectrometer (UVS)
  • An infrared imager/spectrometer (JIRAM)

Explanation:

Each mission of NASA has a specific set of instruments that it uses to perform scientific experiments on the desired heavenly body. In case of Juno, the mission for Jupiter has a series of instruments that would study domains of gravitational forces, magnetic effect, particle detection, radiation detection, UV/IR imaging, and plasma experiments.
