Which feature is located nearest a continent

1 answer:

8 0

The submarine canyon is the feature located nearest the continent. The Submarine canyon is any class of narrow steep-sided valley that cuts into the continental slope and continental rises of the oceans, it is sometimes extending well into the continental shelf, have a nearly vertical walls, and occasionally have a canyon wall heights of up to 5km, from canyon floor to the canyon rim, as with the Great Bahama Canyon. A submarine canyon originates either on the continental shelf or within the continental slopes. The submarine canyon is the main pathways by which the material such as stones and sand reach the deep sea.

a student attaches a 0.5 kg object to a 0.7 m string and rotates the object around her head and parallel to the ground. how much

Marina CMI [18]

The object would have a centripetal acceleration <em>a</em> of

<em>a</em> = (12 m/s)² / (0.7 m) ≈ 205.714 m/s²

so that the required tension in the string would be

<em>T</em> = (0.5 kg) <em>a</em> ≈ 102.857 N ≈ 100 N

A 2020 kg car traveling at 14.2 m/s collides with a 2940 kg car that is initally at rest at a stoplight. The cars stick together

velikii [3]

Answer:

The answer is 3,064x $e^{-4}$

Explanation:

When the collision happens, the momentum of the first car is applied to the both of them.

So we can calculate the force that acts on both cars as:

The momentum of the first car is P = 2020 kg x 14.2 m/s = 28,684 kg.m/s
The acceleration of both cars after the crash is going to be a = P / mtotal which will give us a = 28,684 / (2020+2940) = 5.78 m/s
Since the second car was initially not moving, the final acceleration was calculated with the momentum of the first car.

Now we can find the force that acts on both of them by using the formula F = m.a which will give us the result as:

F = (2020+2940) x 5.78 = 28,684

The friction force acts in the opposite direction and if they stop after moving 2.12 meters;

Friction force is Ff = μ x N where μ is the friction coefficient and the N is the normal force which is (2020+2940) x 10 if we take gravitational force as 10, equals to 49,600.
F - Ffriction = m x V
28,684 - μ x 49,600 = 4960 x 5.78
μ = 3,064x $e^{-4}$

Figure 13 shows a child’s toy . The toy hangs from a hook in the ceiling.

Grace [21]

The number of oscillations of the toy in a second is 1.25.

<h3>What is frequency?</h3>

This is the number of complete oscillation of an object is a given period.

The given parameter:

Frequency of the toy, F = 1.25 Hz

The frequency of an object is calculated as follows;

$f = \frac{n}{t} \\\\$

where;

n is the number of oscillations
t is the time of motion

The number of oscillations of the toy in a second is calculated as follows;

$1.25 = \frac{n}{1} \\\\n = 1.25$
