Answer:
Explanation:
Let the direction in which he peddles makes an angle of θ with north across
Sinθ = 2 / 3.4
θ = 36 degree ( west of north )
b )
component of his velocity along the north = 3.4 cos 36
= 2.75 m /s
time required = 85 / 2.75 s
= 31 s
From the options provided in the question, the measurement which is not an SI base unit is volume.
<h3>What is SI base unit?</h3>
This is referred to as the standard and fundamental unit of measurement of various quantities or variables which is defined arbitrarily and not by combinations of other units.
Volume is a quantity which is derived from the combination of lengths in a three-dimensional manner which is why the formula is length× breadth×height and the unit is cm³. This is gotten from the combination of the unit of length which is cm.
This is therefore the reason why volume was chosen as the most appropriate choice.

Well if we divide both numbers by 5, you get 2 meters per second. Multply this by 3600seconds per hour and you get 7200 meters per hour. There are 1609.34 meters in a mile, so divide 7200 by 1609 to get 4.5 miles per hour
Answer:
Speed, mass and acceleration
Explanation:
A scalar quantity is a quantity that has only magnitude but no direction while a vector quantity has both magnitude and direction.
According to the question, the row that has two scalars and one vector is speed, mass and acceleration.
The two scalars in this row are speed and mass while the vector quantity there is the acceleration.
Acceleration has direction since it possess direction. A body accelerating will do so in a particular direction. Speed and mass doesn't possess any direction. Mass only specify the magnitude of the body but no clue as to which direction is the body moving towards.
Speed also only specify the
total distance covered with respect to time but not the direction of the direction.
Answer:
No
Explanation:
The Earth lies in one of the outer arms of the Milky Way galaxy. The Milky way that you see is the central portion of the galaxy that is visible. It consists of millions of stars, star clusters, dust and gas. The stars, dust and gas are part of the Milky Way only. It is a dense band. It obscures any outside view beyond the galaxy. Thus, you are not able to see any distant galaxies in the this band.
