A 48.9 kg meteor is moving in outer space. If a 8.6 N force is applied opposite the direction of motion, what is the deceleratio

nalin [4]

Answer:

The deceleration is 0.18 m/s²

Explanation:

Hi there!

Using Newton´s second law, we can calculate the deceleration:

∑F = m · a

Where:

∑F = the sum of all forces in a given direction.

m = mass of the object.

a = acceleration.

Solving for a:

∑F/m = a

The only force acting on the meteor is the applied force of 8.6 N. So, the acceleration will be:

8.6 N / 48.9 kg = a

a = 0.18 m/s²

The deceleration is 0.18 m/s² or, in other words, the acceleration is -0.18 m/s²

Have a nice day!

The total charge that an automobile battery can supply without being recharged is given in terms of Ampere-hours. A typical 12-V

anyanavicka [17]

Answer:

7 hours

Explanation:

The total charge contained in the battery is

$Q = 49 A \cdot h$

And this is a charge, since it is a current multiplied by a time:

$Q=It$

The current drawn by each headlight (which is the charge consumed per second) is

$I=3.5 A$

Since we have two headlight, the total current drawn is

$I=3.5 \cdot 2 = 7 A$

Therefore, the total charge consumed by the two headlights each hour is

$q = I \cdot h = 7 A \cdot h$

So, the time before the battery is dead is

$t=\frac{Q}{q}=\frac{49 Ah}{7Ah}=7 h$

A 35-year-old patent clerk needs glasses of 50-cm focal length to read patent applications that he holds 25 cm from his eyes. Fi

Natali5045456 [20]

Answer:

28.57 cm

Explanation:

We are given that

Focal length, $f=50 cm$

Distance of application from his eyes,s=40 cm

$\frac{1}{s}+\frac{1}{s'}=\frac{1}{f}$

$\frac{1}{40}+\frac{1}{s'}=\frac{1}{50}$

$\frac{1}{s'}=\frac{1}{50}-\frac{1}{40}=\frac{4-5}{200}$

$s'=\frac{200}{-1}=-200 cm$

s=25 cm

Substitute the values

$\frac{1}{25}-\frac{1}{200}=\frac{1}{f'}$

$\frac{8-1}{200}=\frac{1}{f'}$

$\frac{1}{f'}=\frac{7}{200}$

$f'=\frac{200}{7}=28.57 cm$

What are the major steps of solar system formation in the correct order?

Gala2k [10]

Answer:(1) Pre-solar nebula

(2). Planet formation

Explanation:

Nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud.

One of the collapsing fragments called the pre-solar nebula formed what became the Solar System.

The planet can also be formed by accretion. Accretion is a process in which planets began as dust grains in orbit around the central protostar.

When the terrestrial planets were forming, they remained immersed in a disk of gas and dust.
