When the forces acting on a stationary object are unbalanced, the object will
A. remain stationary
B. begin moving and speed up
C. remain moving at a constant speed
D. No effect
Answer:
B
Explanation:
Well it is certainly not no effect. Something has to happen. Not D.
If the balances are unbalanced it means that there is a force left over that can cause an acceleration. The speed is not constant when there is an acceleration. Not C
Unbalanced forces mean that there has to be something happening. Unless the friction cannot be overcome, there will be motion. Not A. But it is your second best answer if there is friction.
The answer I think you are intended to give is B.
when the net force of opposite forces is zero , the forces are
A. not even
B. unequal
C. unbalanced
D. balanced
Sound travels at different speeds in different mediums. Rank the three mediums sound can travel to from fastest to slowest.
Answer:
Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids.
Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves.
Which of ONE of the following four elements has the most metallic properties?
The atomic numbers of the elements are listed below.
12
14
16
17
Answer:
12 (Magnesium- Mg)
Explanation:
Looking at the four numbers, we have:
Magnesium, Silicon, Sulfur, and Chlorine.
We can eliminate two of the answers immediately just by looking at the periodic table.
Sulfur and Chlorine are on the nonmetal side of the periodic table. So that's definitely not it. That leaves Magnesium and Silicon.
Silicon is a Metalloid. Magnesium is an Alkaline earth Metal.
Metaloids are elements that have a mix of both metal and nonmetal properties (luster, how it feels, etc.). Since it's a MIX and Magnesium is just straight METAL-
We can say Magnesium has the most metallic properties.

Measuring a liquid's volume indicated the capacity ______ of the holds it. The most common units for expressing liquid volumes are _____ and milliliters.
Answer:
Measuring, comparing and estimating liquid volumes are taught using metric units like liters and milliliters and customary units like quart, pints, gallons and more. Capacity is actually the amount of liquid in the container, which is also the volume of a liquid.

A car with a mass of 2000 kg accelerates at 6 m/s'at a green light. What is the car's force?
Answer:
Car's force is 12000 N.
Explanation:
→ Force = Mass × Acceleration
→ Force = 2000 kg × 6 m/s²
→ Force = 12000 NWhat are tides? the regular daily rises and falls in sea level caused by the gravitational attraction of the Moon and Sun on Earth the regular weekly rises and falls in sea level caused by the gravitational attraction of the Moon on Earth the regular weekly rises and falls in sea level caused by the gravitational attraction of the Moon and Sun on Earth the regular daily rises and falls in sea level caused by the gravitational attraction of the Moon on Earth the regular daily rises and falls in sea level caused by the gravitational attraction of the Sun on Earth
Answer:
the regular daily rises and falls in sea level caused by the gravitational attraction of the Moon and Sun on Earth.
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Generally, the gravitational pull of the Moon cause visible changes on planet Earth's surface.
This ultimately implies that, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.
The various types of ocean tides based on the position of the Earth, Moon and the Sun are;
I. Neap tides.
II. Spring tides.
III. Low tide.
IV. High tide.
V. Brown tide.
VI. Rip tide.
VII. Red tide.

The weight of the fluid that an object displaces is equal to the buoyant force acting on the object is
spring force
Archimedes Principle
buoyant force
Hooke's Law
Answer:
Archimedes' Principle
Explanation:
Its because Archimedes' Principle states "that the buoyant force on an object is equal to the weight of the fluid displaced by the object.... If you want to know the buoyant force on an object, you only need to determine the weight of the fluid displaced by the object."

The speed of a wave with a frequency of 2 Hz (2/s), an amplitude of 3 m, and a wavelength of 10 m is
options:
0.2 m/s.
12 m/s.
5 m/s.
20 m/s.
Answer:
5 m/s
Explanation:
your welcome
The speed of a wave equals to Wavelength and Frequency. The SI unit of speed of wave is m/s. Thus, option D is correct.
What is speed of wave?The speed of wave is distance travelled by the wave in given time. It is related to both wavelength and frequency. Wavelength is measured in meters and frequency in hertz.
From the givens:
Frequency(f) = 2 Hz.
Wavelength(λ) = 10m.
Amplitude = 3m ( Amplitude does not affect the speed of wave)
Speed (v) = λ × f
= 10 × 2
= 20 m/s.
Therefore, the speed of the wave is 20 m/s. Hence, Option D is correct.

In the oxygen cycle, oxygen is
(Choose one):
1.) added to and removed from the atmosphere by photosynthesis.
2.) added to the atmosphere by cellular respiration and removed by photosynthesis.
3.) added to the atmosphere by decomposers and removed by photosynthesis.
4.) added to the atmosphere by photosynthesis and removed by cellular respiration and combustion.
Answer:
4.) added to the atmosphere by photosynthesis and removed by cellular respiration and combustion.
Explanation:
The atmospheric cycle is a biogeochemical cycle and is a transition between the oxidation state in ions, oxides, and molecules. The largest reservoir on the earth for oxygen island or lithosphere. The crust and mantle together make up 99.5% of oxygen by volume. The rest is found in the air that 21%, 22% in the biosphere, and 33% in the hydrosphere.6. An excited dog runs full-speed toward his owner who has just returned home from
school. If he runs north along their driveway for a distance of 45 m and takes 5.2 s to get
there, what is his average velocity?
Please answer in comments with work !!:)
Answer:
v = 8.65 m/s
Explanation:
Given that,
Distance covered by the doge, d = 45 m
Time taken, t = 5.2 s
We need to find its average speed. The total distance covered divided by the total time taken is called the average speed of an object. So,
[tex]v=\dfrac{45\ m}{5.2\ s}\\\\=8.65\ m/s[/tex]
So, the average speed is 8.65 m/s.

A +6.33 uC charge q1 is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. What is the value of q2?
Answer:-4.1858
Explanation: I hate Acellus
If A +6.33 μC charge q₁ is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. then the value of q₂ = 4.23 μC.
What is coulomb's law ?Electrostatic force is a force of attraction or repulsion between two unlike or like charges respectively. when like charges come closer to each other, they gets repel by one another and it gets attracted for unlike charges. Force of attraction or repulsion between two point charges are given by coulomb's law. The force of attraction between two charges are given by coulomb's law.
the law states that the force of attraction or repulsion between two point charges is directly proportional to product of magnitude of both the charge and inversely proportional to square of the distance between them.
i.e. F ∝ q₁q₂
F ∝ 1/r²
F ∝ q₁q₂/r²
F = kq₁q₂/r²
where k is proportionality constant k = 1/4π∈₀ = 8.9×10⁹
In this problem,
Given,
q₁ = 6.33×10⁻⁶ C
F = 0.115N
r = 1.44m
q₂ = ?
putting this values in the equation,
0.115 = 8.9×10⁹×6.33×10⁻⁶ ×q₂÷1.44²
q₂ = 4.23 μC.
