Answer:

The planet lacks a solid surface and the temperature is too low

Explanation:

Jupiter does not have solid surface as it is made up of swirling gases, mainly hydrogen(90%) and helium(~10%). The swirl comes from massive wind with speed of 335 miles/hour. The temperature in cloud of Jupiter is 145°C which is too low for water to remain in liquid state as the temperature range for liquid water is 0°C to 100°C.

In a certain process, the energy of the system decreases by 250 kJkJ. The process involves 480 kJkJ of work done on the system.

BigorU [14]

Answer:

-730KJ

Explanation:

According to the first law of thermodynamics;

Let the total energy of the system be ∆E

Let heat be q and let work the w

Since the energy decreases ∆E is negative

Since work is done on the system w= positive

So;

- 250 = 480 + q

q = -250 - 480

q=-730KJ

A box rests on the back of a truck. The coefficient of friction between the box and the surface is 0.32. (3 marks) a. When the t

cricket20 [7]

Answer:

Part a)

here friction force will accelerate the box in forward direction

Part b)

a = 3.14 m/s/s

Explanation:

Part a)

When truck accelerates forward direction then the box placed on the truck will also move with the truck in same direction

Here if they both moves together with same acceleration then the force on the box is due to friction force between the box and the surface of the truck

So here friction force will accelerate the box in forward direction

Part b)

The maximum value of friction force on the box is known as limiting friction

it is given by the formula

$F = \mu mg$

so we have

$F = ma = \mu mg$

now the acceleration is given as

$a = \mu g$

$a = (0.32)(9.8) = 3.14 m/s^2$

Why do scientist study fossils?

zhuklara [117]

Scientists study fossils of plants, animals, and other organisms in order to better understand what life was like on Earth many years ago and how it has changed over time. Fossils are important evidence for the theory of evolution.
