Answer:
A cleaning product that contains a base.
Explanation:
Ren should use a cleaning product that contains a base. This is because bases readily react with lipids (fats), the kind of compound that makes up grease. A base would break down the grease, forming soap, which would then easily wash away.

A person jogs 4.0 km in 32 minutes, then 2.0 km in 22 minutes, and finally 1.0 km in 16 minutes. What is the jogger's average speed in km per minute?
Answer:
0.0928km/min (4dp)
Explanation:
To find the jogger's speed in km per minute, we just need to divide the number of km jogged by the time in minutes it took to jog that distance. This will give us the distance they jogged every minute which is their speed.
4km in 32 minutes:
4/32 = 0.125km/min
2km in 22 minutes:
2/22 = 0.091 (3dp)km/min
1km in 16 minutes:
0.0625km/min
Now to find the average speed of these 3 speeds, we just add them all together and divide by how many values there are (3 values).
Average (mean) = [tex]\frac{0.125+0.091+0.0625}{3}[/tex]
Average = 0.2785/3
Average speed of jogger = 0.0928 (4dp) km/min

What voltage produces a current of 100 amps with a resistance of 50 ohms?
Answer:
To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)

A volleyball dug out by the opponent popped straight up into the air. It takes 2.05 seconds for the ball to reach its peak. Determine the height to which the ball flies. So far, I got the givens of t=2.05 seconds x=? a=9.8 meter per seconds squared final velocity=0 m/s they might be wrong though so help please!!!!
Answer:
The height to which the ball flies is 86.6 m.
Explanation:
Given that,
Time = 2.05 sec
Acceleration = 9.8 m/s²
We need to calculate the initial velocity of volleyball
Using equation of motion
[tex]v=u-at[/tex]
Where, u = initial velocity
a = acceleration
t = time
Put the value into the formula
[tex]0=u-9.8\times(2.05)^2[/tex]
[tex]u=41.2\ m/s[/tex]
We need to calculate the height of the the ball
Using equation of motion
[tex]v^2=u^2-2ah[/tex]
Put the value into the formula
[tex]0=(41.2)^2-2\times9.8\times h[/tex]
[tex]h=\dfrac{(41.2)^2}{2\times9.8}[/tex]
[tex]h=86.6\ m[/tex]
Hence, The height to which the ball flies is 86.6 m.
A physics student drops a water balloon from an upstairs window. The window is 26.45 m
from the ground. How long does it take for the balloon to hit the ground? (Round to the
nearest tenth)
Answer:
Explanation:
Given:
Distance S = 26.45m
Using the equation of motion
S = ut+1/2gt²
26.45 = 0+1/2(9.81)t²
26.45 = 4.905t²
t² = 26.45/4.905
t² = 5.392
t = 2.528s
Hence the it took the balloon 2.52s to reach the ground

Answer:

Explanation:
a. speed, distance , very large
What is a light year?Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.
The speed of light measures the space traveled by electromagnetic waves every second.
In a vacuum, electromagnetic waves propagate at a constant velocity of approximately 299,792,458 meters per second.
In other words we can state that the speed of light refers to the rate that light travels through empty space.
Light-year is a unit of measurement used to calculate distances in astronomical space, i.e. where planets, stars, comets and so on are found.
The distances between the stars are huge, so to measure the immense dimensions of the universe requires the application of a special unit of measurement: the light year.
Because of this gigantic distance, the distance between the stars is measured in light years.

is Babe Ruth?
And can you give me 3-5 sentences about her
1. Ruth first gained fame as a pitcher.
Although best remembered for swatting a prodigious 714 home runs and slugging .690, which remains a major-league record, Ruth was one of baseball’s most dominant left-handed pitchers in the 1910s. He won 89 games in six seasons with the Boston Red Sox, including 24 in 1917, and helped the team win three World Series titles. Ruth only pitched five games for the New York Yankees as his position switched to outfielder after being sold by Boston before the 1920 season.
2. He did not retire as a New York Yankee.
Ruth’s major-league career not only started in Boston, it ended there as well, but not with the Red Sox. Discarded by the Yankees as his performance waned, Ruth signed with the National League’s Boston Braves in 1935 in the hopes of becoming the team’s manager the following season. When it became clear that his skills had deteriorated and the promise would not be kept, Ruth ended his 22-year career after just 28 games in a Braves uniform.
3. Ruth was not a unanimous choice for the Baseball Hall of Fame.
A year after his retirement, Ruth was among the five initial inductees elected to the new National Baseball Hall of Fame under construction in Cooperstown, New York. In spite of Ruth’s amazing career statistics, 11 of the 226 voters left him off their ballots, and the “Sultan of Swat” trailed Ty Cobb as the leading vote-getter. Ruth’s plaque in Cooperstown refers to him as baseball’s “greatest drawing card,” and proving the point, the Hall of Fame last month opened a new exhibit on Ruth to coincide with the centennial of his first big-league season.
Explanation:
Answer:
He began his career as a pitcher: Ruth was both a left-handed pitcher and left-handed batter.
His father died in a fight with a family member
Ruth played for the Boston Red Sox (1914-1919), the New York Yankees (1920-1934) and briefly the Boston Braves (1935).

What collides and creates a movement of heat called conduction?
A. photons
B. compounds
C. Molecules
D. atoms
Answer:
c.
Explanation:
Molecules collide and create a movement of heat called conduction.
What is conduction?
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction
