Answer:
5.9 m
Explanation:
v=6m/s
H=5m
h=0.17m
g=10 m/s
First we find the time in which ball reaches the entrance of coffee can. For this purpose the ball has to travel a distance S vertically downward such that
S= 5-0.17 = 4.83 m
While falling down Vi =0
g= 10 m/sec2
t = ?
S=vit+1/2 gt2
==> 4.83=0+0.5×10×
==> 4.83=5×
==> =4.83/5 = 0.97
==> t= 0.98 sec
So in this time the ball reaches the coffee can height level. Now let's calculate horizontal distance covered by the ball in this time.
Horizontal distance = horizantal velocity × time
= 6 × 0.98 = 5.9 m
Answer
given,
time = 10 s
ship's speed = 5 Km/h
F = m a
a is the acceleration and m is mass.
In the first case
F₁=m x a₁
where a₁ = difference in velocity / time
F₁ is constant acceleration is also a constant.
Δv₁ = 5 x 0.278
Δv₁ = 1.39 m/s
a₁ = 0.139 m/s²
F₂ =m x a₂
F₃ = F₂ + F₁
Δv₃ = 19 x 0.278
Δv₃ = 5.282 m/s
a₃=Δv₂ / t
a₃ = 0.5282 m²/s
m a₃=m a₁ + m a₂
a₃ = a₂ + a₁
0.5282 = a₂ + 0.139
a₂=0.3892 m²/s
F₂ = m x 0.3892...........(1)
F₁ = m x 0.139...............(2)
F₂/F₁
ratio = 
ratio = 2.8
Answer:
Energy is carried by the electric and magnetic fields
Explanation:
Electromagnetic waves consist of electric fields and magnetic fields which oscillate perpendicularly to the direction of propagation of the waves (for this reason, they are called transverse waves).
Electric fields and magnetic fields both possess energy, and this energy is carried through space by the wave. Note that electromagnetic waves do not carry matter, but only energy (in fact, they do not have mass). Moreover, electromagnetic waves are the only type of waves that do not need a medium to propagate: in fact, they can also travel through a vacuum.
