Solids have a definite lattice structure

The molecules of liquids and gases are quite apart that the attraction between them is quite weak compared to that of the solids. Hence, they only take the shape of their containers. On the other hand, solids have definite shape because of their well-structured lattice and that the molecules are closely packed together.

If a system has 225 kcal of work done to it, and releases 5.00 × 102 kj of heat into its surroundings, what is the change in int

vovikov84 [41]

We can solve the problem by using the first law of thermodynamics:

$\Delta U = Q-W$

where

$\Delta U$ is the change in internal energy of the system

$Q$ is the heat absorbed by the system

$W$ is the work done by the system on the surrounding

In this problem, the work done by the system is

$W=-225 kcal=-941.4 kJ$

with a negative sign because the work is done by the surrounding on the system, while the heat absorbed is

$Q=-5 \cdot 10^2 kJ=-500 kJ$

with a negative sign as well because it is released by the system.

Therefore, by using the initial equation, we find

$\Delta U=Q-W=-500 kJ+941.4 kJ=441.4 kJ$

An object is thrown with velocity v from the edge of a cliff above level ground. Neglect air resistance. In order for the object

musickatia [10]

Answer:

Explanation:

The range of a projectile is given by R = v²sin2θ/g.

For maximum range, sin2θ = 1 ⇒ 2θ = sin⁻¹(1) = 90°

2θ = 90°

θ = 90°/2 = 45°

So the maximum horizontal distance R is in the range 0 < θ < 45°, if θ is the angle above the horizontal.

Based on the image, which is not a wavelength?

ki77a [65]

The distance that is not a wavelength in the image is C to E.

<h3>What is wavelength?</h3>

Wavelength is the distance between two successive crests or two successive trough or crest to trough.

It is also the distance over which the wave's shape repeats.

Based on the image, the following are wavelengths;

A to E, this is wavelength because it is between a crest and a trough.
B to F, this is wavelength because it is between two successive crest.
D to H, this is wavelength because it is between two successive trough.

Thus, the distance that is not a wavelength in the image is C to E.
