projected. Calculate the net force acting on
the object. If this object is 10 kg,
how/where will it accelerate?
Answer:
the free-body diagram shows the vectors for all the forces acting on the body. The resultant vector found by summing all the individual vectors represents the net force. Since F = ma, the acceleration vector will point in the same direction as the net force, with a magnitude of F / m

Which are examples of chemical weathering? Choose the two correct answers. (1 poir
-rock breaking apart during a rock slide
-an insect digging a hole in rock for its home
-oxidation of certain metals in rock
-an increase in temperature in daytime causing a rock to crack
-acid rain breaking down compounds in rock statues
Oxidation of certain metals in rock and acid rain breaking down compounds in rock statues are examples of chemical weathering.
What is chemical weathering?
When chemicals are diluted and dissolved in water, they seep and percolate down the surfaces of rocks, causing chemical weathering. Chemical weathering occurs in humid tropical regions and other places with high temperatures and a sufficient supply of water.
The reaction of chemicals in water or air causes minerals to change in composition as chemical weathering takes place. Additionally, this causes the breakdown of rocks. Leaching is the process of carrying away some components of rock breakdown through rocks and soil.
These materials may eventually be transported by the water to rivers and the sea. The oceans' saltiness comes from this source. Oxidation, the breakdown of calcium carbonate, and acid rain breaking down compounds in rock statues by chemical reaction are examples of chemical weathering.

If a metal has a mass of 78.2 g and a volume of 11.4 mL, what is its density?
Answer:
6.86g/mL
Explanation:
The density of the metal would be approximately 6.859 grams per milliliter (g/mL).
Given that the mass (m) is 78.2 g and the volume (V) is 11.4 mL, we can plug these values into the formula:
Density is a physical property that quantitatively expresses how much mass is contained within a given volume of a substance. In other words, it is a measure of how tightly packed the particles or molecules of a material are. Mathematically, density is defined as the mass of an object (or substance) divided by its volume. It is often denoted by the Greek letter "ρ" (rho).
Density is defined as mass per unit volume. The formula for density is:
Density (ρ) = Mass (m) / Volume (V)
Density (ρ) = 78.2 g / 11.4 mL
Now, let's calculate the density:
Density (ρ) = 6.859 g/mL
So, the density of the metal is approximately 6.859 grams per milliliter (g/mL).

suppose the blocks collide elastically. picking the positive direction to the right, what is the velocity of the bigger block after the collision takes place?
We have that with v_1 =v this goes to show that the velocity of the bigger block after the collision takes place is v
From the question we are told
Suppose the blocks collide elastically. picking the positive direction to the right, what is the velocity of the bigger block after the collision takes place?
Generally the equation for Momentum is mathematically given as
P=mv
Therefore
[tex]m_1v_2=m_2v_2[/tex]
Hence
[tex]v_1=\frac{m_2v_2}{m_1}[/tex]
Therefore
[tex]v_1=\frac{mv_2}{2m}\\\\v_1=\frac{v_2}{2}[/tex]
Hence
[tex]2v+v=v_1+v_2\\\\v_1=v[/tex]
Now
with v_1 =v this goes to show that the velocity of the bigger block after the collision takes place is v

Measure a pencil, end to end. Draw a sketch of the pencil and show your measurements. If you were to balance the pencil horizontally on your finger, where do you think it would be balanced? Note this on your sketch, and write down your hypothesis (distance from each end) and your prediction.
Now test your hypothesis. Balance the pencil on your finger horizontally. When it is balanced, your finger is at the center of gravity. Note and make a mark where your finger is in relation to each end of the pencil.
Measure from one end of the pencil to where your finger balanced it. Show this on your sketch, and record the data it in your chart.
Repeat steps b-c a second time for the pencil.
Repeat steps a - d using a pen and crayon as well.
What are your results? Compare your results with your hypothesis and then write an explanation in a conclusion. Which item has a center of gravity closer to the actual center that you measure?
Answer:

On a trip you travel at a constant speed of 25 kilometers per hour South for 1 hour. You then turn West and travel at a constant speed of 50 kilometers per hour for 2 hour. Calculate your velocity for the trip.
Answer:
41.66 km/h
Explanation:
Calculate the distance of 1st travel :
v = d/t
25 km/h = d/1 h
d = 25 km/h × 1 h
d = 25 kmCalculate the distance of 2nd travel :
v = d/t
50 km/h = d/2 h
d = 50 km/h × 2 h
d = 100 kmCalculate the velocity of trip :
v = d/t
v = (25 + 100)/(1 + 2)
v = 125 km/3 h
v = 41.66 km/hSo, my velocity for the trip is 41.66 km/h
