Magnitude of acceleration = (change in speed) / (time for the change) .
Change in speed = (end speed) - (start speed)
= (2 m/a) - (8 m/a) = -6 m/a .
Time for the change = (end time) - (start time)
= (13 sec) - (10 sec) = 3 sec .
Magnitude of acceleration = (-6 m/a) / (3 sec)
= -2 m/a per second .
(That's the best I can do with the ambiguous units.
What unit of speed is 'm/a' ? Is that "miles per afternoon" ?)
Answer:
cell swell and burst(b)
Explanation:
This process is called hemolysis. it also occurs in a red blood cell.
Answer: The five general characteristics of the nearest stars are the brightness, color, surface temperature, size, and mass.
Explanation:
The mass of a star can be described as being measured with our sun at 1 solar mass. One star can equal the size of our sun. There is one star named, Rigel, that is bigger than the Earths sun. Each star will vary in its density.
The size of the star, as stated above, can be the size of our sun and sometimes larger. The size is measured by solar radii.
Stars vary in their temp. They range anywhere from -273.15 degrees Celsius to 50,000 K. The temp is based on the Kelvin scale.
The stars brightness are always based on luminosity and magnitude.
The stars colors will vary and is based on the temperature of the surface of the star. Some stars are red in color, white in color, and some even have a bluish color.
Density is the ratio of a substance's mass to its volume. On the other hand, according to Archimedes' principle, the volume of water displaced is equal to the volume of the object placed on the water. Thus, the density of the metal is equal to 8.39 mL. So, the density would be
Density = 32.5 g/8.39 mL = 3.87 g/mL
