The Eastern coastline of South America and West coastline of Africa looked like they fit together
Because the light colors will only work on a dark background, as dark colors will only work on a light background. If light color were on the white background not only will it be nearly impossible to read, the letters with have to be much larger for older people to read or see. Therefore, Black letters on a white background is most common. But a Black background with white letters could also work, kind of like a chalkboard.
Answer
there are strong attractive forces between atoms of liquids with a high viscosity
Explanation:
viscosity:
Viscosity is the state of being sticky and thick . There are strong attractive forces between atoms of liquids with a high viscosity on the other hand in non viscous liquid there are weak attractive forces between atoms of liquids. A semi fluid liquid like jelly is said to be viscous. Viscosity increases with stronger inter molecular forces at normal temperature. Viscosity decreases as temperature increases

Answer:
<em>The height of the cliff is 78.4 m</em>
Explanation:
<u>Horizontal Launch Motion</u>
When an object is thrown horizontally with a speed v from a height h, it describes a curved path exclusively ruled by gravity until it hits the ground.
The horizontal component of the velocity is always constant because no acceleration acts in that direction, thus:
The vertical component of the velocity changes in time because gravity makes the object fall at increasing speed given by:
Where g is the acceleration of gravity.
The maximum horizontal distance traveled by the object can be calculated as follows:
If the horizontal distance and the speed are known, we can solve the equation above for h:
The car leaves a cliff at a horizontal speed of v=15 m/s and hits the ground d=60 m from the shoreline. Thus the height of the cliff is:
Calculating:
h = 78.4 m
The height of the cliff is 78.4 m
Answer with Explanation:
We are given that
Velocity of uranium=v=0.94 c
Speed of piece A relative to the original nucleus=
Speed of piece B relative to the original nucleus=
Velocity of piece A observed by observer
Substitute the values
Velocity of piece B observed by observer
The velocity of piece A and piece B as measured by an observer in the laboratory are not same.
