Kinetic energy = 0.5*M*V^2
Q7-
0.5*3*(2^2)= 6J
Q8a-
0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J
the second ball has more kinetic energy.
Q8b-
at the max height, all the kinetic energy is converted to potential energy,
gravitational potential energy is = M*g*h
that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:
First ball:
2kg*9.81(g)*10m = 196.2J
Second ball
4kg*9.81*10m= 392.4J
The second ball has more potential energy
A 2nd-century hysteria was caused by the belief that the uterus could move freely within the body in search of fluid and cause specific symptoms depending on the areas the uterus was displaced to. Called the wandering womb disorder, the womb was believed to be a living thing within a living thing.
Answer:
The nights are shorter.
Explanation:
Summer normally begins on June 21 and ends on September 20 in the northern hemisphere. This season is characterized by the higher temperatures of the year than sloping, and in which both animals and plants are more active. Summer is characterized by the days being longer than the nights.
Answer:
It is important because plants would not be able to produce food for themselves, so the plant would die. Animals that feed on plants would not be able to survive, and animals that feed on other animals would die too because they would not have any food.
A mutation which occurs when a base is introduced into the DNA sequence before transcription begins will lead to frame-shift of a single base on the DNA sequence resulting in nonfunctional protein from the transcribed mRNA.
Explanation:
This change either through addition or deletion of a single base in the codon sequences of the DNA will modify the amino acid codes and will result in nonfunctional proteins after transcription.
This mutation will just result in change of a single base, i.e., it would be added either to the enhancer region or the silencer region of the sequence before the promoter which initiates transcription.
The mRNA produced due to mutated DNA sequence after the deletion or insertion point will be read as out of frame thus resulting in nonsense protein.
