Answer:
dominant season is SUMMER
Explanation:
Latitude on the planet is the angle measurement from the so-called equator or midpoint of the Earth's sphere, therefore latitude values can range from 0º to 90º.
Low latitude values, values close to zero degrees, are very close to the central part of the planet, so when you plan to tilt in or orbit the Sun, this part is almost fixed, therefore the solar irradiation is very constant. throughout the year, consequently the dominant season is SUMMER
3) Magnets are used to separate steel cans from aluminum cans in recycling plants. How can
they be used for this?
(Will give brainliest if it's a proper answer)
Answer:
Since steel contains iron (a magnetic metal), the magnets will attract the steel cans since aluminum is not magnetic. This is used to separate the steel cans from the aluminum cans so they can be recycled separately.

A car is traveling at 10 m/s. 10 seconds later the car is traveling 40 m/s. What is the car’s acceleration?
Answer:
a = 3 m/s^2
Explanation:
Vi = 10 m/s
Vf = 40 m/s
t = 10 s
Plug those values into the following equation:
Vf = Vi + at
40 = 10 + 10a
---> a = 3 m/s^2
The car is traveling with an initial velocity of 10 m/s, a final velocity of 40 m/s in the time period of 10 seconds, then the acceleration of the car is 3 m/s².
What is acceleration?Acceleration describes a change in an object's velocity. By accelerating, decelerating, or changing direction of motion, an object's velocity may change.
An apple falling to the ground, the moon orbiting the earth, and a car stopping at a set of traffic lights are a few examples of acceleration. With the aid of these illustrations, we may better see that acceleration occurs whenever a moving object modifies its direction, speed, or both.
The given values according to the question are,
Initial velocity, u = 10 m/s
Final velocity, v = 40 m/s and,
Time, t = 10 seconds.
Use the equation of motion to find the acceleration,
v = u + at
40 = 10 + (a)10
a = 30/10
a = 3 m/s².
Hence, the acceleration of the car is 3 m/s².

What is the reason for heat transfer from one substance to another?
A.
difference in pressure
В.
difference in volume
C.
difference in temperature
D.
difference in mass
Answer:
C
Explanation:
A book that weighs 0.35 kilograms is kept on a shelf that’s 2.0 meters above the ground. A picture frame that weighs 0.5 kilograms will have the same gravitational potential energy as the book when it’s raised to a height of ____
meters.
(Use PE = m × g × h, where g = 9.8 N/kg. )
Answer:
E p = m · g · h
E p ( book ) = 0.35 kg · 9.8 m/s² · 2 m = 6.86 J
E p ( picture frame ) = 6.86 J
( same gravitational potential energy as the book )
6.86 = 0.5 · 9.8 · h
6.86 = 4.9 h
h = 6.86 : 4.9
h = 1.4 m
Answer: 1.4 M
Look at the diagram B. What is happening in diagram B ?

A simple pendulum makes 540 complete oscillations in a minute, so its frequency is ........... HZ
A-3
B-6
C-9
D-12
Answer:
a
Explanation:
time=540×60
=32400
f=1÷t
=1÷32400
f=3.09
f=3
The frequency is 3 Hz.
To calculate the frequency of the pendulum, the values given are
t = 540 minute
What is frequency of simple pendulum?The frequency of the simple pendulum can be described through the pendulum moves and come back to its own position for the specific period of the time. Also the pendulum frequency depends upon its length and mass.
Thus, frequency formula can be,
ω = √g/l
T = 2π / ω
Frequency, f = 1 / T = ω / 2π
As we have to find the frequency, the time period will be reciprocal.
f = 1/ T Hz.
t = 540 per minute
= 540 × 60 seconds
= 32400 seconds
f = 1 / 32400
= 3.08 × 10 ⁻⁶
f = 3 Hz
The frequency thus calculated as 3Hz.
Hence, Option A is the correct answer.

Someone fires a 0.04 kg bullet at a block of wood that has a mass of 0.5 kg. (The block of wood is sitting on a frictionless surface, so it moves freely when the bullet hits it). The wood block is initially at rest. The bullet is traveling 300 m/s when it hits the wood block and sticks inside it. Now the bullet and the wood block move together as one object. How fast are they traveling?
Answer:
22.22m/s
Explanation:
The momentum before a collision = momentum after collision so...
work out the momentum of the first object (the bullet)
its p = mv
0.04 kg × 300 m/s = 0.54 kg × v
rearrange this to find v which is 0.04 x 300 = 12
so 12 = 0.54 x v
12/0.5 = v
v = 22.22m/s

• table tennis ball
• metre rule
• stop clock
• calculator
• light gate
• data logger
describe how the student can use this, or other additional equipment, to determine an accurate value for the acceleration of free fall (g). the student need not use all the equipment. show clearly what measurements should be taken and how the students should use these in determining (g). describe one source of error and how this might affect the value of (g).
(6 marks/year9/gcse)
Explanation:
Use a meter stick, small metal ball, stopwatch, calculator.
Have the students mark off a vetrtical distance from which to drop the metal ball. Ready the stopwatch, and start when the object is dropped and stop when the object contact the ground. Repeat 5 times and average the stopwatch times.
Now, use the formula d=vo+(1/2)at^2
There's no initial velocity, so d=(1/2)at^2
We know time and distance, so we can solve for a, acceleration.
2d=at^2
(2d)/(t^2)=a
Now, input the numbers gathered in the experiment in meters and seconds.
One source of error is human error (stopwatch timing)

He does a battery generate electrical energy?
Plssssss help me no one wants to help me——— power plants use generators to generate electricity for homes and businesses. Some generators work by spinning a coil of wire inside a magnet, as shown in the image. To keep the coil of wire spinning, it’s often attached to a turbine, which is s as n axle with fan blades. Different kinds of power plants use different methods to spin the turbine to make electricity. What’s one way a power plant might spin the turbine?
Answer:
There are a many ways to produce electricity. Electrons can flow between certain different materials providing a current, as in a common battery. While reliable and portable, chemical batteries run down quickly. To provide the large amounts of steady power demanded by modern societies, large power plants have been built. Most power plants make electricity with a machine called a generator.
A 1925 Turbine Rotor
A 1925 turbine rotor for a Westinghouse generator, Image #21.035, Science Service Historical Image Collection, National Museum of American History
Generators have two important parts: the rotor (which rotates) and the stator (which remains stationary). Generators use the principle of electro-magnetic induction, which exploits the relation between magnetism and electricity. In large AC generators, an outer shell with powerful magnets rotates around a stationary "armature" which is wound with heavy wire. As they move, the magnets induce an electric current in the wire.
It is important to recognize that electricity is not mined or harvested, it must be manufactured. And since it's not easily stored in quantity, it must be manufactured at time of demand. Electricity is a form of energy, but not an energy source. Different generating plants harness different energy sources to make electric power. The two most common types are "Thermal Plants" and "Kinetic Plants".

Why does it take a long time for a train to come to a complete stop?
Answer:
Trains stop in their own time.
Every freight train, every situation, every load is different. The distance it takes to halt a train in an emergency is based on multiple factors: the speed when the brakes are applied, the track's incline, the number of cars hooked behind the locomotives and the loading of those cars, the "brake delay" inherent in the train's hydraulic system, the friction-causing metallurgy of the wheels and tracks, the weather.
Even the engineer behind the controls can't know on any given day how long it would take to stop the train.
"There is no specific rule of thumb on that," said Greg Udolph, general manager of the Texas State Railroad, a freight and tourist line in East Texas running from Palestine to Rusk. "If the track is wet with dew it changes. Everything that can affect it does. A train takes as long to stop as it takes to stop. Sometimes it can be a mile. Sometimes it's less, sometime's it's more."

Explanation:
If my angular velocity slows from 30 Hz to 20 Hz in 72°, what is my deceleration?
Answer:
The deceleration is -7.85x10³ rad/s².
Explanation:
The angular speed (ω) is related to frequency (f) as follows:
[tex] \omega = 2\pi f [/tex]
When the frequency is 30 Hz the angular speed is:
[tex] \omega_{i} = 2\pi f = 2\pi*30 Hz = 188.5 rad/s [/tex]
Now, when the frequency is 20 Hz the angular speed is:
[tex] \omega_{f} = 2\pi*20 Hz = 125.7 rad/s [/tex]
Finally, the angular acceleration (α) can be found using the following equation:
[tex] \omega_{f}^{2} = \omega_{i}^{2} + 2\theta \alpha [/tex]
Where:
θ: is the angular displacement = 72°
[tex] \alpha = \frac{\omega_{f}^{2} - \omega_{i}^{2}}{2\theta} [/tex]
[tex] \alpha = \frac{(125.7 rad/s)^{2} - (188.5 rad/s)^{2}}{2*72*\frac{2\pi rad}{360}} = -7.85 \cdot 10^{3} rad/s^{2} [/tex]
Therefore, the deceleration is -7.85x10³ rad/s².
