A fundamental force , is your answer .
Answer:
The helicopter was 1103.63 meters high when the package was dropped.
Explanation:
We consider positive speed as a downward movement
y: height (m)
t: time (s)
v₀: initial speed (m/s)
Δy = v₀t +
gt²
Δy= 15
×15 s +
×9.81
×(15 s)²
Δy= 1103.63 m
Evidence of Chemical Change:
A car rusting
Leaves changing in October
The glow of a light bulb
A white cloudy substance occurs after mixing two substances
Burning toasts
A candle being lit
Evidence of Physical Change:
Water boiling
Yellow and blue paints mixed together
Wax melting
Crushing a rock with a hammer
Hope this helps!
Have a great day!
Work done on the crate is 1411.2 J
Explanation:
Work done is defined as the product of force and the distance moved by the object. The unit of work done is in joules and denoted by the symbol J.
Work done = F * d
where F represents the force and d represents the distance moved by the object.
mass = 72 kg , distance moved by the object is given by 2.0 m
Force F = mass * gravity = 72 * 9.8
= 705.6 N =706 N.
Work done = 706 * 2.0 = 1412 J.
