Answer:

The caves were caused by erosion from waves.

Explanation:

The cave is an inhospitable but oxygen-filled underground space, large enough to be examined and studied by man, especially for its peculiar formations and the different life forms contained in these spaces. There are several types of cave, among these types we can mention the marine caves that are created by the erosion of the waves.

Waves are formed by the joint action of wind and water, their effects are noted in lake, coastal and riverbank environments. The impact of the waters (ebb and flow) on the banks causes the disintegration of material, which remains suspended and is later deposited at the bottom of rivers, lakes, seas etc. This disintegration is what causes erosion and the origin of the marine caves.

Hey there!

Your answer: The caves were caused by erosion from waves.

Have you ever seen a sea cave? They're quite interesting to look at. But, some wonder, how does this occur? There's a famous science picture that many know, it's a rock that use to be nothing but a big rock with no hole in side. But, over years, after erosion, it slowly turned into a 'n'. It's quite cool! But, with caves, like from what this question is asking, sea caves come from erosion, which usually comes from waves.

Your answer: The caves were caused by erosion from waves.

e-lub [12.9K]

Assume a maximum stopping acceleration of g/2 where g is acceleration due to gravity.

Answer:

2.99 m/s

Explanation:

Stopping distance, s = 3 ft = 0.914 m

final velocity, v = 0

a = g/2 = 4.9 m/s²

Use third equation of motion:

$v^2-u^2 = 2as$

substitute the values to find the speed of train:

$0 -u^2 = 2\times -4.9 \times 0.914 \\u^2=8.96 \\u=2.99 m/s$

A charge of 1.5 µC is placed on the plates of a parallel plate capacitor. The change in voltage across the plates is 36 V. How m

belka [17]

Answer:

Energy stored in the capacitor is $U=2.7\times 10^{-5}\ J$

Explanation:

It is given that,

Charge, $q=1.5\ \mu C=1.5\times 10^{-6}\ C$

Potential difference, V = 36 V

We need to find the potential energy is stored in the capacitor. The stored potential energy is given by :

$U=\dfrac{1}{2}q\times V$

$U=\dfrac{1}{2}\times 1.5\times 10^{-6}\times 36$

U = 0.000027 J

$U=2.7\times 10^{-5}\ J$

So, the potential energy is stored in the capacitor is $U=2.7\times 10^{-5}\ J$ . Hence, this is the required solution.

iren [92.7K]

The energy becomes 0.50 times in 6.72 s.

Let E represent the oscillator's initial energy, Et be the energy's final value at time t, where A is its beginning amplitude, At amplitude at time t, be. as the oscillator's energy increases to 0.50 times its initial value. We can replace the oscillator's total energy for the energy at time t to obtain the amplitude as shown below.

Et=0.50E

k(4₂)² = (0.5) - kA²

(4₂)² = (0.5) A²

At = 0.71A

So, the amplitude of the oscillator becomes 0.71 times its initial ar

0.71A = = A(0.96)¹2

log(0.71)

log(0.96)

8.4

So, the time taken for n oscillation is obtained as,

t = n (0.800 s)

= (8.4) (0.800)

= 6.72 s
