Answer:

A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.

The difference between scalar and vector quantities is simply the direction we always consider when dealing with vector quantities.

Scalar quantities are those quantities that have only magnitude but no direction. Examples are;

Vector quantities are those quantities that have both magnitude and direction. Examples are;

The difference between scalar and vector quantities is simply the direction we always consider when dealing with vector quantities.

Therefore, direction is the difference between them.

The constant acceleration of the object is [tex]0.414\ m/s^2[/tex].

The acceleration of the object is constant, and the values at the three different positions is the same.

[tex]s = v_0 t + \frac{1}{2} at^2\\\\37.7 = v_o(9.6) +\frac{1}{2} a(9.6)^2\\\\ 37.7 = 9.6v_0 + 46.08a[/tex]

[tex]39.3 = v_o(18.048) +\frac{1}{2} a(18.048)^2\\\\ 39.3 = 18.048v_0 + 162.87a[/tex]

[tex]37.7 = 9.6v_0 + 46.08a\\\\39.3 = 18.048v_0 + 162.87a\\\\18.048: \ \ 680.41 = 173.261v_0 + 831.651a\\\\9.6: \ \ \ \ -(377.28 = 173.261 v_0+ 1563.552a)\\------------------\\303.13 = -731.901a\\\\-a = \frac{303.13}{731.901} \\\\-a = 0.414 \ m/s^2\\\\|a| = 0.414 \ m/s^2[/tex]

Answer:

Newton's laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not change its motion unless a force acts on it. ... In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction

Answer:

Humans are pouring carbon dioxide into the atmosphere much faster than plants and oceans can absorb it. These gases persist in the atmosphere for years, meaning that even if such emissions were eliminated today, it would not immediately stop global warming.

Explanation:

By absorbing increased carbon dioxide from the atmosphere, the ocean reduces the warming impact of these emissions were they to remain in the atmosphere. However, carbon dioxide dissolved into the ocean causes seawater to acidify, threatening the ability of shellfish and corals to build their skeletons and affecting the health of other fish and marine species—many that are important to coastal economies and food security.“The increasing load of carbon dioxide in the ocean interior is already having an impact on the shellfish industry, particularly along the U.S. West Coast,” said Richard Feely of NOAA’s Pacific Marine Environmental Laboratory, leader of NOAA’s West Coast acidification-observing network and a co-author of the study. “We have been working with the industry to provide an early warning system against the most severe impacts of rising carbon dioxide levels.”  Rik Wanninkhof, an oceanographer at NOAA’s Atlantic Oceanographic and Meteorological Laboratory and another co-author, added: “A critical question that warrants continued observations of the ocean is if this uptake can be sustained and what might happen to the Earth’s atmosphere if the ocean is unable to absorb continued increased carbon dioxide.”“A higher concentration of carbon dioxide in our atmosphere would aid photosynthesis, which in turn contributes to increased plant growth,”

Answer:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2).

Explanation:

Acceleration can be calculated by dividing the change in velocity (measured in metres per second) by the time taken for the change (in seconds). The units of acceleration are m/s/s or m/s 2.

Weightlifter 1 has more power as compared to weightlifter 2 because it takes longer time to lift the weight.

Work is a physics term used to describe the transfer of energy that takes place when an object changes above a distance because of an external force, at least some of which is given in the vector of the dislocation.

The element of the force acting all along the path multiplied by the length of the path can be used to calculate work if the force is constant.

Mathematically, this idea is expressed as W = fd, where W is the effort and f is the force multiplied by d, the distance. Work is completed whenever the force is applied at an angle of with regard to the displacement.

As per the given information in the question,

The power is work done per unit time or if the time will increase, the power will decrease. Power and time are inversely proportional to each other. So, the weightlifter 1 is taking less time than it has more power compared to weightlifter 2.

Here the power of the microwave is 0.2kW . And as we know that ,

So from the definition , we have ;

[tex]\sf\longrightarrow Power =\dfrac{Work}{time}[/tex]

[tex]\sf\longrightarrow Power =\dfrac{Energy}{time}[/tex]

[tex]\sf\longrightarrow 0.2kW = \dfrac{10^4 J }{t} \\[/tex]

[tex]\sf\longrightarrow 0.2 * 1000 W = \dfrac{10^4 J }{t} [/tex]

Cross multiply ,

[tex]\sf\longrightarrow t = \dfrac{ 10^4 }{ 0.2 * 10^3}s=\dfrac{10^4}{2*10^2} s [/tex]
