When the earth passes through orbit that has the trail of dust and gas after the comet passes through the orbit, the are chnaces of meteor shower.

Here, in the given image, the comet path is intersecting the earth's orbit.

Thus, the chances of meteor shower are very large if there is the comet whose trail of dust or gas has just passes through the nearby the earth orbit.

A force does work on an object if a component of the force is called
ivanzaharov [21]

Explanation:

The work done by an object is given by :

W=Fd\cos \theta

Here,

F is force

d is displacement

\theta is the angel between F and d.

If the angle between force and displacement is 0, then the work done is equal to, W=Fd.

So, a force does work on an object if a component of the force is parallel to the displacement of the object.

A gardener uses a water hose to fill a 30.0 L bucket. The gardener notes that it takes 1.00 min to fill the bucket. A nozzle wit
GalinKa [24]

Answer:

The distance can the water be projected is 4.51 m

Explanation:

The speed of the water in the hose is equal to:

v1 = R/A1

If we solve the continuity for v2:

v2 = R/A2 (eq. 1)

The equation for the vertical position is:

yf = yi + vy*t - (1/2)gt²

yi = 0

vy = 0

Clearing t:

t=\sqrt{\frac{-2y_{f} }{g} } (eq. 2)

The equation for position is:

xf = xi + vxt = 0 + v2t = v2t (eq. 3)

Replacing equation 1 and 2 in equation 3:

x_{f} =\frac{R}{A_{2}  } \sqrt{\frac{-2y_{f} }{g} } =\frac{30}{0.5} \sqrt{\frac{(-2)*(-1)}{9.8} }*\frac{1000}{60}  =451.75cm=4.51m

A backpack has a mass of 8 kg. It is lifted and given 54.9 J of gravitational potential energy. How high is it lifted? Accelerat
sweet [91]
Potencial Energy=hma
Where
Potencial Energy =E= 54.9J
h=?
m=8kg
a=9.8m/s^2
You need to know that 1 J=1(kgm^2)/s^2

Isolate h=E/(ma)
h=(54.9)/(8*9.8)
