What is the density of 244 grams of aluminum that has a volume of 90 ml?
Answers
Answer:
The answer is 2.71 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 244 g
volume = 90 mL
So we have
[tex]density = \frac{244}{90} = \frac{122}{45} \\ = 2.71111111...[/tex]
We have the final answer as
2.71 g/mLHope this helps you

1. During an accident investigation, a detective measures the skid marks that a car
left to determine how fast it was initially moving before stopping when it hit a
light pole. The detective measures the distance to be 40 meters. The detective
receives the car's braking acceleration to be 4.57m/s2 from the manufacturer's
manual. Help the detective by solving how fast the car was initially going before
he hit the light pole? Someone please help I’ll give you a brainlest
Answers
Answer:
19.12 m/s.
Explanation:
The following data were obtained from the question:
Final velocity (v) = 0 m/s
Breaking Acceleration (a) = – 4.57 m/s²
Distance (s) = 40 m
Initial velocity (u) =.?
The initial velocity of the car can be obtained as illustrated below:
v² = u² + 2as
0² = u² + (2 × –4.57 × 40)
0 = u² + (– 365.6)
0 = u² – 365.6
Collect like terms
u² = 0 + 365.6
u² = 365.6
Take the square root of both side
u = √365.6
u = 19.12 m/s
Therefore, the car was initially moving at 19.12 m/s.

Explanation:
The magnitude of the player's average velocity during the drill is 0 m/s.
The given parameters;
length of the court, L = 30 mnumber of times, = 3time of motion, t = 60 sAverage velocity is change in displacement per change in time of motion.
[tex]\Delta \bar v = \frac{\Delta x}{\Delta t}[/tex]
where;
[tex]\Delta x[/tex] is the change in displacementThe change displacement is zero, since the player moved forward and back to the exact initial position.

Answers
Answer:
Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.
Explanation:
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

The equivalent formulas for velocity, acceleration, and force using the relationships covered for UCM, Newton’s Laws, and Gravitation.
We know that,
Velocity :
The velocity is equal to the rate of position of the object.
[tex]v=\dfrac{dx}{dt}[/tex]....(I)
Acceleration :
The acceleration is equal to the rate of velocity of the object.
[tex]a=\dfrac{dv}{dt}[/tex]....(II)

Put the value of p
[tex]F=\dfrac{d(mv)}{dt}[/tex]
[tex]F=m\dfrac{dv}{dt}[/tex]
Put the value from equation (II)
[tex]F=ma[/tex]
This is newton’s second laws.
Gravitational force :
The force is equal to the product of mass of objects and divided by square of distance.

Where, m₁₂ = mass of first object
m= mass of second object
r = distance between both objects

Alice and Tom dive from an overhang into the lake below. Tom simply drops straight down from the edge, but Alice takes a running start and jumps with an initial horizontal velocity of 25 m/s. Neither person experiences any significant air resistance. Just as they reach the lake below,
Answers
Answer:
The velocity of Alice (25 m/s) will be greater than that of Tom (0), when they reach the lake below.
Explanation:
Given;
initial horizontal velocity of Tom is zero since he dropped straight down from the edge.
initial horizontal velocity of Alice is 25 m/s.
Their respective horizontal velocity when they jumped is the same as when they reach the lake below.
If we compare their velocities when they reach the lake, one will be greater than the other, if we neglect air resistance.
Thus, the velocity of Alice (25 m/s) will be greater than that of Tom (0), when they reach the lake below.

A softball is thrown perfectly vertically (straight-up) at 18 m/s.
a) How high will it go?
b) Find the total time the ball is in the air.
Answers
Answer:
a) y = 16.51 [m]
b) t = 1.83 [s]
Explanation:
To solve this problem we must use two kinematics equations, the first to determine the height to which the ball reaches, and the second equation to determine how long it lasts in the air.
[tex]v_{f} ^{2}= v_{i} ^{2} - (2*g*t)\\[/tex]
where:
Vf = final velocity = 0
Vi = initial velocity = 18 [m/s]
g = gravity acceleration = 9.81[m/s^2]
t = time [s]
Note: the negative sign of the Equation indicates that the acceleration of gravity acts in the opposite direction to the movement of the ball. The final velocity is zero, since the ball reaches its maximum altitude when the velocity is zero.
Now replacing:
0 = (18)^2 - (2*9.81*y)
y = 16.51 [m]
b)
[tex]v_{f} = v_{i} - (g*t)[/tex]
0 = 18 - (9.81*t)
t = 1.83 [s]

C.

D.

Answers
Answer:
B. Induction
Explanation:
Just had it on study island
When objects are charged by induction, they do not need to touch each other. Hence, option (B) is correct.
What are different process of charging?A charged particle is touched to a conductive medium as part of the charging by conduction process. In this manner, the conductor receives the charges from the charged substance.
Rubbing one particle against another causes electrons to move from one surface to another during the charging by friction process.
An object is charged using induction charging, which doesn't require physical contact between the charged objects. The charged particle is held close to an uncharged conductive substance that is grounded on a neutrally charged material during the charging by induction process.
When a charge is transferred between two objects, an uncharged conductive substance produces an oppositely polarized charge. These were the many charge transfer techniques.
