Answer:
the acceleration will be 10 m/s^2
Explanation:
the force applied to an object and the acceleration of the object are directly proportional, as Newton's second law states:
where
F is the net force applied to the object
m is the object's mass
a is the object's acceleration
in the first example, a force F=45 N is applied to the object, giving it an acceleration of a=5 m/s^2. Therefore, the mass of the object is
In the second example, the force is doubled, so it will be F=90 N. The mass is still m=9 kg, so the acceleration will be
Answer:
if he were to land on concrete, he would most likely die and stop all momentum and for the water, he'd most likely live/die (mostly live) and slow momentum to a stop and rise up to the surface
Explanation:
that's the explanation now i gotta execute order 66
Answer:
Combustion reaction resulted in formation of Hydrogen gas.
Explanation:
When zinc and Hydrogen Chloride (HCl) are mixed together, it is a oxidation reduction process. To be specific, a combustion reaction takes place. It is an exothermic reaction. Exothermic reactions involve oxygen and generate . Here, due to this exothermic reaction, Hydrogen gas is being produced which results in the formation of bubble and inflation of balloon.
Answer:
Yes. You are correct. Great job!
Explanation:
The density of the gold is calculated to be "19,300 kg/m³".
<u>Explanation:</u>
Given:
Volume = 2cm³
Mass = 38.6 grams.
To Find:
Density of the gold = ?
Solution:
Density is obtained by dividing mass of the sample by its volume and it is given in the units of kg/m³.
Mass in grams is converted into kg as,
1 g = 0.001 kg
38. 6 g = 
Now we have to convert cm³ to m³ as,
1 cm³ = 10⁻⁶ m³
2 cm³ = 2 × 10⁻⁶ m³
So Density = 
Physical properties of Gold:
- It is Malleable and ductile.
- It is a corrosion resistant element.
