A book with a mass of 1kg is dropped from a height of 3m . What is the potential energy of th book when it reaches the floor?
Answer:
30 J
Explanation:
height = 3 m
mass = 1kg
acceleration due to gravity = 10m/s²
Potential Energy = mass× gravity × height
= 1kg ×10m/s²× 3m
= 30 J

A cannonball with a mass of 50 kilograms and a golf ball with a mass of 0. 8 kilograms are dropped in a vacuum from a height of 10 meters. Compare the acceleration of each object as they fall.
It's gonna take a huge amount of time and effort, and we're gonna spend a huge amount of money, to build a vacuum chamber big enough to do this experiment.
So when we're finally ready to try it, the cannonball and golf ball will make a kind of cute experiment, but let's make it really interesting. Let's ALSO try it with a feather, an apple, a watermelon, a tennis ball, a basketball, a coffeepot, a chair, an old computer, a set of dishes, a trombone, a bicycle, a math book, a TV set, a gallon of milk, a skateboard, a shotgun, a concrete block, a car, a waterbed, a schoolbus, a battleship, your dog, and my wife !
Drop every single one of them from a height of 10 meters.
Every single one of them accelerates at 9.8 m/s² as it falls, takes 1.429 seconds to reach the floor, and hits the floor at a speed of 14 m/s. The feather, the schoolbus, and my wife stay together all the way down.
The only way this doesn't happen is if ...
-- you do this experiment in some other place that's not Earth, or
-- you throw one of the objects and you don't just drop it, or
-- the vacuum chamber has a leak and some air gets into it.
Because that's how gravity works.

Solve for the resultant displacement of the two vectors: A = 2.3 km at 45 degrees B = 4.8 km at 90 degrees
Answer:
The resultant of the vector is 6.63 km
Explanation:
Given;
vector A = 2.3 km 45°
vector B = 4.8 km 90°
The vectors in the x - direction is given by;
Aₓ = 2.3 km Cos 45° = 1.6263 km
Bₓ = 4.8 km Cos 90° = 0
The sum of the vectors in x -direction is given by;
∑X = 1.6263 km + 0 = 1.6263 km
The vectors in the y - direction is given by;
Ay = 2.3 km Sin 45 = 1.6263 km
By = 4.8 km Sin 90° = 4.8 km
The sum of the vectors in y -direction is given by;
∑Y = 1.6263 km + 4.8 km = 6.4263 km
The resultant vector is given by;
R = √(X² + Y²)
R = √[(1.6263)² + (6.4263)²]
R = 6.63 km
Therefore, the resultant of the vector is 6.63 km
The resultant displacement of the two vectors A and B is 6.63 Km and this can be determined by using the given data.
Given :
The two vectors: A = 2.3 km at 45 degrees B = 4.8 km at 90 degrees.
In order to determine the resultant displacement, first, determine the vector in x-direction:
[tex]\rm A_x=2.3cos45=1.6263 \;Km[/tex]
[tex]\rm B_x=4.8cos90=0 \;Km[/tex]
Now, the sum of the vectors is given by:
[tex]\rm \sum X=1.6263+0=1.6263\;Km[/tex]
In order to determine the resultant displacement, first, determine the vector in y-direction:
[tex]\rm A_y=2.3sin45=1.6263 \;Km[/tex]
[tex]\rm B_y=4.8sin90=4.8 \;Km[/tex]
Now, the sum of the vectors is given by:
[tex]\rm \sum Y = 1.6263+4.8=6.4263[/tex]
Now, the resultant vector is given by:
[tex]\rm R = \sqrt{X^2+Y^2}[/tex]
[tex]\rm R=\sqrt{(1.6263)^2+(6.4263)^2}[/tex]
R = 6.63 Km
The resultant displacement of the two vectors A and B is 6.63 Km.

Explanation:
Arrange the following events in the mantle convection process. Use numbers 1-5.
a. Lithospheric plates move in the asthenosphere due to rising and sinking of
materials.
b. The decomposition of radioactive elements causes heat in the interior part of
the Earth
c. Heat slowly rises to the mantle and creates convection current.
d. Heat moves to the core.
e. The process repeats as cycle.
Answer:
1) Lithospheric plates move in the asthenosphere due to rising and sinking of materials is 1.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core
5) The process repeats as cycle.
Explanation:
Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .
The process of mantle convection start with
1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core, cools down by conduction and convection of heat.
5) The process repeats as cycle.
The proper and correct arrangement of events in the mantle convection process are:
1. The decomposition of radioactive elements causes heat in the interior part of the Earth.
2. Heat moves to the core
3. Heat slowly rises to the mantle and creates convection current.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process repeats as a cycle.
Convection is considered to be one of the most efficient ways through which heat is transported from the interior of planet Earth to the surface.
Mantle convection can be defined as the very slow transfer of heat due to the movement of Earth's solid silicate material within the mantle.
Basically, the slow creeping of the mantle causes a transfer of heat from the white-hot core to the brittle lithosphere during mantle convection.
Furthermore, the heating of the mantle takes place from below (the core) and it rises upward in hotter regions while it sinks down in colder regions.
The proper and correct arrangement of events in the mantle convection process are:
1. Heat is caused in the interior part of the Earth due to the decomposition or decay of radioactive elements.
2. Heat moves to the core.
3. Heat slowly rises from the Earth's core to the mantle and creates convection current in the asthenosphere, which is the plastic layer of the mantle.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process is then repeated as a cycle.

When the light turns green, Mark accelerates straight down the road at 1.8 m/s2 for 8 seconds. What is his final velocity at the end of those 8 seconds?
Answer:
14.4m/s
Explanation:
To calculate the final velocity (V), we use the formula:
v = u + at
Where; v = final velocity (m/s)
u = initial velocity (m/s)
a = acceleration (m/s²)
t = time (s)
According to the provided information in this question, v = ?, u = 0m/s, a = 1.8m/s², t = 8s
Hence, v = u + at
v = 0 + (1.8 × 8)
v = 0 + 14.4
v = 14.4m/s
Therefore, his final velocity at the end of those 8 seconds is 14.4m/s.

what happens to the wave length and frequency of a wave as it crosses a different medium and speeds
Answer: SEE EXPLANATION!
Explanation:
When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same.

Explanation:
Answer:
[tex]F_{g} = \frac{m}{d^{2} }[/tex] shows the relationship between gravity and mass.
Explanation:
According to the Newton's law of gravitation, the gravitational force between two bodies is,
[tex]F_{g} = G.\frac{m_{1}.m_{2} }{d^{2} }[/tex]
here [tex]m_{1} and m_{2}[/tex] are masses, d is distance between them.
What is Newton's law of Gravitation ?It states that gravitational force acting two bodies is directly proportional to the product of masses and inversely proportional to the square of the distance between them.
In above formula ,
If [tex]m_{1} = 1 and[/tex] [tex]m_{2} = m[/tex]
so [tex]F_{g} = G \frac{m}{d^{2} }[/tex]
Since G is constant ,
[tex]F_{g}[/tex] ∝[tex]\frac{m}{d^{2} }[/tex]
Hence second option is correctly showing relationship between gravity and mass.

How long would it take to swim across a lake that is 350 meters, if you swam at 9 m/sec
Answer:
[tex]\boxed {\tt t\approx 38.89 \ s}[/tex]
Explanation:
Time can be found by dividing the distance by the speed.
[tex]t=\frac{d}{s}[/tex]
The distance is 350 meters.
The speed is 9 meters per second.
[tex]d= 350 \ m \\s= 9 \ m/s[/tex]
Substitute the values into the formula.
[tex]t=\frac{350 \ m}{9 \ m/s}[/tex]
Divide. Note that the meters or "m" will cancel each other out and the seconds or "s" will move to the numerator.
[tex]t=\frac{350 }{9 \ s}[/tex]
[tex]t=\frac{350 \ s}{9}[/tex]
[tex]t=38.8888889 \ s[/tex]
Round to the nearest hundredth. The 8 in the thousandth place tells us to round the 8 to a 9.
[tex]t \approx38.89 \ s[/tex]
It will take about 38.89 seconds to swim 350 meters at 9 meters per second.
