two spheres A and B are projected off the edge of a 1.0 m high table with the same horizontal velocity . sphere A has a mass of 20.g and sphere B has a mass of 10.g.
     If both spheres leave the edge of the table at the same instant, sphere A will land
a.    at some time after sphere B.
b.    at the same time as sphere B.
c.    at some time before sphere B.
d.    There is not enough information to decide.​

Answers

Answer:

c. because A will land first becuase its heavier :)

Explanation:

what would the net force be on the box in the problems shown below.( both force and direction).​ for all four diagrams. please explain answers.​

Answers


Answer:
A) object moves 20 N [West] or -20 N [East]
B) object moves 6 N [South] or -6 N [North]
C) object moves 90 N [West] or -90 N [East]
D) object does not move and is at rest*

*Rest means 0


Why:

A)both forces from north and south that are pushing against the object neutralize each other. Assume that north is positive and south is negative: 20 [N] + (-20) [S] = 0
On West and east, you can see that west has a greater force. Assume that west is negative and east is positive: 50 [E] + (-70) [W] = -20 [E]

an unladen swallow flies 5 m/s how far has the bird traveled after 1 minute?

Answers

Answer: 300m

1 minute = 60s

the unladen swallow can fly: 60.5 = 300 (m)

Explanation:

Flying 5 m/s is the same as 300 m/minute. Therefore, it is 300 meters.

A D N A template that consists of nine nucleotides is shown. Five nucleotides have already been added to the complementary strand that is growing from left to right along the template. The left end of the growing strand is labeled 5 prime, and the right end is labeled 3 prime. The left end of the template strand is labeled 3 prime, and the right end is labeled 5 prime. An incoming d T T P has three phosphate groups. Arrows indicate that the two outermost phosphate groups split off as the d T M P with the remaining phosphate group is about to join to the 3 prime end of the growing strand.Figure 1. Model showing details of adding a deoxythymidine monophosphate (dTMP) nucleotide to a growing strand of DNAThe features of this model provide evidence for which explanation of why all growing strands are synthesized in a 5 to 3 direction?A. The two strands need to be antiparallel to bond properly.B. Thymine and adenine would not bond properly if the strand grew from 3 to 5.C. The translation of mRNA occurs in the 5 to 3 direction; therefore, the growing DNA strand must also grow in the 5 to 3 direction.D. The phosphate group, attached to the 5 carbon of the dTMP, forms a covalent bond with the oxygen atom attached to the 3 carbon of the growing strand.
