Suppose you are driving in a convertible with the top down at constant speed. You point a rifle straight upward and fire it. In

lyudmila [28]

Answer:

Explanation:

When we are moving in a convertible with constant speed so as per inertia all the objects are moving with same speed as that the speed of convertible.

So here we can say that bullet when shot from the rifle then its speed is same as that of convertible in horizontal direction

So here we can say that if air friction is absent then bullet will move same horizontal distance as the distance moved by you in the convertible

so after it it will reach again at the same position then the displacement of you and bullet is same in horizontal direction so we can say that correct answer will be

A supply plane needs to drop a package of food to scientists working on a glacier in Greenland. The plane flies 90.0 m above the

romanna [79]

Answer:

d = 771.3m

Explanation:

Let's first calculate the time of flight:

$Yf = Yo+Voy*t-g*t^2/2$ where Voy=0. Solving for t:

$t = \sqrt{2*90/9.8} =4.285s$

Now we calculate the horizontal displacement, wihch is the distance from the target to drop the package:

Xf = d = Vox*t

d = 180*4.285 = 771.3m

How does enormous energy get released from the sun

vova2212 [387]

Answer:

By nuclear fission

Explanation:

<u>The sun generates enormous energy through the process of nuclear fusion.</u>

<em>The core or the innermost part of the sun is characterized by high temperature and pressure. These two factors cause the separation of nuclei from electrons and the fusion of hydrogen nuclei to form a helium atom. </em>

During the fusion process, energy is released.

The electrical force on a 2-c charge is 60 n. the electric field where the charge is located is

Kazeer [188]

The electrical force acting on a charge q immersed in an electric field is equal to
$F=qE$
where
q is the charge
E is the strength of the electric field

In our problem, the charge is q=2 C, and the force experienced by it is
F=60 N
so we can re-arrange the previous formula to find the intensity of the electric field at the point where the charge is located:
$E= \frac{F}{q}= \frac{60 N}{2 C}=30 N/C$
