Answer:
h = 1.8 m
Explanation:
The initial velocity of the glove, u =- 6 m/s
We need to find the maximum height of the glove. Let it is equal to h. Using equation of kinematics. At the maximum height v = 0
[tex]v^2-u^2=2ah[/tex], h is the maximum height and a = -g
[tex]0^2-(6)^2=2\times (-10)\times h\\\\h=\dfrac{36}{20}\\\\h=1.8\ m[/tex]
Hence, it will go up to a height of 1.8 m.

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).

An ice skater weighs 500 [N]. He is coasting to the right at a constant velocity of 2 [m/s]. Assume
the ice is frictionless.
What is the net force on the skater?
Answer:
The net force on the skater is zero. ([tex]F_{net} = 0\,N[/tex])
Explanation:
According to Newton's First Law, an object is at equilibrium when either it is at rest or moves at constant velocity, which means a net force of zero. Based on the given statement, there are no external forces acting on skate and, therefore, the net force on the skater is zero. ([tex]F_{net} = 0\,N[/tex])
Olivia and Caitlyn want to know whether the wind affects how far a football will travel. They have one student go outside to the football field when it is not windy and throw the football 30 times. They measure how far the ball goes using a meter stick. On a windy day, they have the same student go to the football field and throw the football 30 times. Again, they measure how far the ball goes using the same meter stick. What is the Independent Variable?
Answer:
presence or absence of wind
Explanation:
When establishing a relationship between two variables the effect one variable has on the other is studied. The variable that changes with respect to the other is the dependent variable while the other variable is called the independent variable.
Here the distance the football covers in the presence and absence of wind is studied. So, the presence or absence of wind is the independent variable.
A tennis ball, 0.384 kg, is accelerated at a rate of 187 m/s2 when hit by a professional tennis player. What force does the player's tennis racket exert on the ball?

Joe follows the procedure below to make a compass. 1. Move a magnet from the top of a needle to its point fifty times. 2. Lay the needle on a cork that is floating in a bowl of water. 3. Observe the direction that the needle points. What is the purpose of step 1? to give the needle an electric charge to make the needle sharper to magnetize the needle to flatten the side of the needle
Answer:
C) To magnetize the needle
Explanation: I took the test!
When a magnet is moved away or towards a needle, current is bound to flow through the needle. The answer is to give the needle an electric charge.

What is the mass of 23 mL of a liquid that has a density of 1.5 g/mL?
Answer:
The answer is 34.5 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
volume = 23 mL
density = 1.5 g/mL
We have
mass = 23 × 1.5
We have the final answer as

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.

If an object has two forces acting on it, how can the net force equal 0?
Answer:
Check explanation.
Explanation:
Net force is essentially the sum of the forces enacting upon an object. One example of net force is gravity and normal force. It is commonly accepted that every object has a force acting upon it, even if it is stationary. To give an example, the weight of an object has a force upon the earth but the earth pushes back, essentially meaning that the object will not sink.

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
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.
Which statement accurately describes the motion of the objects in the ticker tape above?
Both objects are speeding up at a constant rate.
One object speeds up before it slows to a stop.
Both objects speed up before stopping.
One object speeds up at a constant rate until it stops.
Answer:
B
Explanation:
One object speeds up before it slows to a stop.
When reading this type of graph, we know that when the points are far apart, then the object is definitely moving quickly. Also again, we know that when the points are besides each other, then we say that the object is moving slow. When the distance that is between the points are changed, the velocity of the object subsequently changes too, and therefore, we say that the object is accelerated. When there are lots of points in one location, we will see that the object is not moving.
This then translates into that
The object(s) at the top begins to slow, eventually, it increases in its speed, going forward, it slows down again, before it finally halts. The object at the bottom on the other hand, starts fast, before slowing down.
then:
"One object speeds up before it slows to a stop "

Answer:a number without a decimal are generally not significant. Isotopes are atoms of same element which have the same atomic number but different number of neutrons. Isotopes of elements are represented in the following way: In an atom, the number of protons is equal to its atomic number.. An atom of an element is neutral in nature so atom contains the same number of protons and electrons.
