Answer:
Time, t = 10 seconds
Explanation:
Given the following data;
Mass = 10kg
Force = 10N
Final velocity = 10m/s
Initial velocity = 0m/s
To find the time;
First of all, we would find the acceleration of the box.
Force = mass * acceleration
10 = 10 * acceleration
Acceleration = 10/10 = 1m/s²
Now, we can find the time by using the first equation of motion;
V = U + at
10 = 0 + 1t
10 = t
Time, t = 10 seconds
Therefore, it will take 10 seconds for the box to come to a complete stop.

What's the name of the compound Cal2?
Answer:
The correct answer is calcium iodide.
Explanation:
Hope this helped Mark BRAINLIEST!!!
The compound with the chemical formula CaI₂ is called calcium iodide.
A compound is a substance formed when two or more elements chemically combine in specific proportions. It is characterized by a distinct chemical composition and properties that differ from the elements it is composed of. Compounds are held together by chemical bonds, which can be either ionic or covalent, depending on the nature of the elements involved.
Calcium Iodide (CaI₂):
Calcium iodide is an ionic compound composed of the elements calcium (Ca) and iodine (I). In this compound, calcium, which is a metal, donates two electrons to iodine, a non-metal, resulting in the formation of a calcium ion (Ca²⁺) and two iodide ions (I⁻). The ions are held together by electrostatic forces of attraction, forming a crystal lattice structure.
Calcium iodide is a white, crystalline solid that is highly soluble in water. It is commonly used in various applications, including as a catalyst in organic reactions, a source of iodine for nutritional supplements, and in the synthesis of pharmaceuticals.
Therefore, The correct answer is Calcium Iodide.

2.A motorcycle’s velocity at the top of the hill is 11.0 m/s. 4.0 seconds later it reaches the bottom of the hill with a velocity of 20.0 m/s. What is the acceleration of the motorcycle?
Answer:
1) as far as I remember
Let's take 20 as vf (final velocity) and 11 as (initial velocity) and 4 as time
So we would use this formula a=vf-vi/t
So 20-11/4

A tungsten wire is 1.5m long and has a diameter of A current of flows through the wire. The resistivity of the wire is 5.6 * 10 ^ - 8 What is the potential difference across the ends of the wire?
Complete Question:
A tungsten wire is 1.5 m long and has a diameter of 1.0 mm. A current of 60 mA flows through the wire. The resistivity of the wire is 5.6 * 10^-8 Ωm. What is the potential difference across the ends of the wire?
Answer:
Potential difference, V = 0.00642 Volts.
Explanation:
Given the following data;
Diameter = 1 mm to meters = 1/1000 = 0.001 m
Length = 1.5m
Current = 60mA = 60/1000 = 0.06 Amperes.
Resistivity = 5.6 * 10^-8 Ωm
To find the potential difference across the ends of the wire;
First of all, we would determine the cross-sectional area of the wire (circle);
[tex] Radius, r = \frac {diameter}{2} [/tex]
[tex] Radius = \frac {0.001}{2} [/tex]
Radius = 0.0005 m
Area of wire (circle) = πr²
Substituting into the above formula, we have;
Area = 3.142 × (0.0005)²
Area = 3.142 × 2.5 × 10^-7
Area = 7.855 × 10^-7 m²
Next, we find the resistance of wire;
Mathematically, resistance is given by the formula;
[tex] Resistance = P \frac {L}{A} [/tex]
Where;
P is the resistivity of the material.
L is the length of the material.
A is the cross-sectional area of the material.
Substituting into the formula, we have;
[tex] Resistance = 5.6 * 10^{-8} \frac {1.5}{7.855 * 10^{-7}} [/tex]
[tex] Resistance = 5.6 * 10^{-8} * 1909611.712 [/tex]
Resistance = 0.107 Ohms.
Now, we can find the potential difference using the formula;
[tex] V = IR[/tex]
Where;
V represents voltage or potential difference measured in volts.
I represents current measured in amperes.
R represents resistance measured in ohms.
Substituting into the formula, we have;
[tex] V = 0.06*0.107[/tex]
Potential difference, V = 0.00642 Volts.
A student has two identical sheets of paper. He crumples one up into a small ball. If he drops the sheet of paper and the ball of paper off a building at the same time, which of the following statements describes the result?
A. The sheet of paper because it is more affected by gravity.
B. The ball of paper hits the ground first because it is more affected by gravity
C. The sheet of paper and the ball of paper hit the ground at the same time.
D. The ball of paper hits the ground first because it has less surface area.
Answer:
B
Explanation:
basically, because the ball "weighs" more now, it will hit the ground quicker. so technically gravity is more affective towards it. the piece of paper kind of floats it's way down. gravity isn't pushing on one force more, but because because the ball weighs more, it technically would be said so. hope this helps!
Answer:
the ball of paper, because it has less surface area.

When an object is moving to the left and slowing down, what direction is the acceleration?
Answer:
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.
Explanation:
If an owl produces two pellets every 24 hours and each pellet contains the remains of 3 prey, how much does it eat in a week? A month?
The owl eats 42 prey in a week and 180 prey in a month.
To calculate how much the owl eats in a week and a month, we need to determine the number of prey consumed in each time period.
In a week:
The owl produces two pellets every 24 hours. So, in one day, it consumes 2 * 3 = 6 prey (since each pellet contains the remains of 3 prey).
In a week (7 days), the owl consumes 6 * 7 = 42 prey.
In a month:
Assuming a month has 30 days (though some months have 31 days or 28/29 days), we can calculate the number of prey consumed in a month.
In a day: 6 prey
In a month (30 days): 6 * 30 = 180 prey.
Hence, the owl eats 42 prey in a week and 180 prey in a month.

Two magnets are attracting each other. One magnet is big and strong; the other is small and weak. The big magnet attracts the small magnet with:
Answer:
magnetism and dipole-dipole interaction
Explanation:
Two magnets are attracting each other, one magnet is big and strong, the other is small and weak, the big magnet attracts the small magnet with a stronger force, and the attraction depends on the size of the magnet.
What is the significance of the magnet and magnetic fields?The attraction between two magnets varies, and that depends upon several factors such as the strength of the force of attraction, which determines the usefulness and functionality of magnets, for example, in industrial settings, strong magnets are often used to lift heavy loads, etc.
Hence, two magnets are attracting each other, one magnet is big and strong, the other is small and weak, the big magnet attracts the small magnet with a stronger force, and the attraction depends on the size of the magnet.

Answer:
B Eight light-minutes
Explanation:
In the case when the distance separated earth and the sun so here we orbit the sun for a 150 million km distance and the light moves would be 300,000 kilometers per second
Now divide this
= 150 million ÷ 300,000 kilometers per second
= 500 seconds
This 500 seconds represent 8 minutes and 20 seconds
Hence, option B is correct
Answer:
B) Eight light-minutes
