A neutron has zero charge but their mass is <span>1.67492716 × 10^-27 kg </span>
The correct answer is D. Tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
Explanation:
The experiment compares the speed of light and sound in different mediums (gas, liquid, and solid). The charts show sound travels faster in a solid medium (ice) than in liquids or gases as the speed in ice was 3200 m/s, while in the liquid was 1500 m/s and in the gas was 346 m/s. Thus, sound waves travel faster in solids, which occurs because for sound to travel particles need to bounce or vibrate, which occurs faster in solids as particles are packed together.
On the other hand, the data about light shows this travels faster in gases (air) because in this medium the speed of light is , while in a solid the speed is . This shows opposite to sound, light travels faster in gases, and therefore, the tightly packed particles of soil only slow down light waves.
friction make non moving objects starts to move
there are different types of force which may help them to move
Answer:6.36 ft
Explanation:
Given
there is 110 ft of deer-resistant
area enclosed must be at least 700 ft^2
Let the length be L
and area of rectangular garden is 110\times L
thus
L=6.36
Therefore Length of garden must be at least 6.36 ft
The magnitude of the electrostatic force is 0.09 N, and the force is attractive
Explanation:
The strength of the electrostatic force acting on a charged particle is given by
where
q is the charge
E is the magnitude of the electric field
For the charge in this problem, we have:
is the electric field
is the charge
Therefore, the force experienced by this charge is
And the negative sign means that the force is attractive: in fact, the charge is negative, while the charge that is producing the field is positive (because the electric field points outward), therefore the negative charge is attracted towards the positive charge that is generating the field.
