Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve

What is one important difference between savannas and temperate grasslands? A. Savannas only rarely experience fires. B. Temperate grasslands are mostly treeless. C. Savannas are inhabited by grazing mammals. D. Temperate grasslands have nutrient-poor soil.
The one important difference between savannas and temperate grasslands
is that Temperate grasslands are mostly treeless.
Temperate grasslands have varying types of plants and animals in the
region. They have very few trees and are mainly dominated by grasses.
The temperate grasslands have lesser amount of rainfall than the
savannas.
The Savannas have different types of plants ranging from shrubs to
woody trees. The temperate grasslands have nutrients due to the
formation of organic matter from dead plants leaves and roots and aren't
generally regarded as having nutrient poor soil.

Why is frog development susceptible to minor environmental changes?
plz help
The correct answer is option B) They go through many developmental changes.
Frogs are amphibians, which means they can live on land and in water. Frogs have permeable skin and lay shellless eggs in water, where their larvae will metamorphose before emerging and entering their terrestrial environment. As a result, they are very sensitive to biological changes and pollutants since, during the maturation phase of a frog, numerous complicated cellular differentiation cycles occur. These cycles are interconnected and are set off by particular signals and reactions. Therefore, disruption in certain environmental factors can affect various developmental changes.
That is why the development of the frog is susceptible to minor environmental changes

how many chromosomes would be found in an allopolyploid plant if its parents had diploid numbers of 2 and 10, respectively?
Answer:
6
Explanation:
The allopolyploid off spring should have 6 chromosome the gametes produced for the diploid number 2 should be 1 and for 10 it should be 5 (n/2) the two gametesof both parents gametes should then fuse ( 1+5 ) giving us 6
or
gamete chromosomes =n÷2
gametes for diploid number 2
N= 2
2÷2 = I
gamete Chromosome = 1
gamete for diploid number 10
N=10
10÷2 =5
Allopolyploid= 5+1
=6
what are the two functional parts of a tRNA
Answer: Transfer RNAs are coded by a number of genes, and are usually short molecules, between 70-90 nucleotides (5 nm) in length. The two most important parts of a tRNA are its anticodon and the terminal 3’ hydroxyl group, which can form an ester linkage with an amino acid.

If two trucks have the same mass, but truck A is traveling 15 km/h, and truck B is traveling 30 km/h, what statement is true? Question 2 options: Truck A has greater kinetic energy. Truck B has less kinetic energy. Truck B will have a greater stopping distance. Truck A will have a greater stopping distance.
Given that the two trucks have the same mass but different velocities, that is truck A is traveling 15 km/h and truck B is traveling 30 km/h, hence Truck B will have a greater stopping distance.
The reason why Truck B will have a greater stopping distance is because it speed is greater hence more distance to cover.
From the following expression
Speed = Distance/Time
Distance = Speed*Time
More on the kinetic Energy
Following from the given problem truck B will also have more kinetic energy because it velocity is more
Formula
KE= 1/2mv^2
Hence the more the velocity for a constant mass the greater the Kinetic energy
