Squid use jet propulsion for rapid escapes. A squid pulls water into its body and then rapidly ejects the water backward to prop

el itself forward. A 1.5 kg squid (not including water mass) can accelerate at 20 m/s2 by ejecting 0.15 kg of water.?

This is a measure of force per unit area.
Vlad1618 [11]
<h2>Answer: Pressure</h2>

<u>Pressure</u> is the force F exerted by a gas, a liquid or a solid on a surface (or area) A.

Its unit according to the International System of Units is Pascal Pa which is equal to N/m^{2} and its formula is:  

P=\frac{F}{A}

You accelerate a 0.43kg football 5m/s2. Calculate the force you applied to the football.
Elza [17]

The force applied on the football is 2.15 Newton.

Given the data in the question;

  • Mass of football; m = 0.43kg
  • Acceleration; a = 5m/s^2

Force applied; F = \ ?

To determine the force applied on the football, we use Newton's laws of motion:

F = m * a

Where m is the mass of the object and a is the acceleration.

We substitute our given values into the equation

F = 0.43kg\ *\ 5m/s^2\\\\F = 2.15kg.m/s^2\\\\F = 2.15N

Therefore, the force applied on the football is 2.15 Newton.

Place the descriptions in the correct categories.
irina [24]

Answer:

At Convergent Boundaries:

Subduction

Island arcs

Volcanic mountains

At Divergent Boundaries:

Mid-ocean ridges

Rift valleys

Plates pulling apart

Magma breaks through crust

Magma flows from cracks

Explanation:

A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.

Divergent boundaries occur in the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.
