Answer:
Forces are defined by both strength and direction
Explanation:
- Force is defined a push or a pull applied on an object.
- It is defined by both strength and direction. This is because force is an example of a vector quantity.
- A vector quantity is a quantity with both magnitude and direction.
- In this case, force is a quantity that has both magnitude and direction, such that the strength of a force is the magnitude of the force while the direction shows direction of the application of force.
- Hence, force has to be defined using both magnitude and direction.
- It is measured in Newtons.
Answer:
Volume in L = 0.028 L
Explanation:
Given data:
Mass of copper phosphate = 27.6 g
Molarity solution = 6.03 M
Volume of solution = ?
Solution:
First of all we will calculate the number of moles of copper phosphate.
Number of moles = mass/molar mass
Number of moles = 27.6 g/ 159.61 g/mol
Number of moles = 0.17 mol
Volume of solution:
Molarity = number of moles / volume in L
By putting values,
6.03 M = 0.17 mol / volume in L
Volume in L = 0.17 mol / 6.03 M
Volume in L = 0.028 L
Answer:
In farm animals, dietary carbohydrates provide well over one-half of the energy needs for maintenance, growth, and production. Glucose is a primary energy source for certain animal tissues and a precursor for lactose synthesis in the mammary gland.
Answer:
True.
Explanation:
Here is an example: Hubble Space Telescope's launch in 1990 sped humanity to one of its greatest advances in that journey. Hubble is a telescope that orbits Earth. Its position above the atmosphere, which distorts and blocks the light that reaches our planet, gives it a view of the universe that typically far surpasses that of ground-based telescopes.
Hubble is one of NASA's most successful and long-lasting science missions. It has beamed hundreds of thousands of images back to Earth, shedding light on many of the great mysteries of astronomy. Its gaze has helped determine the age of the universe, the identity of quasars, and the existence of dark energy.
Answer:
The correct option is 9
Explanation:
The easiest way to balance any combustion equation is to first write the general form. In a combustion reaction the products are always carbon dioxide (CO2) and water (H2O) and the reactants are the organic material plus oxygen (O2).
General Form:
C6H12 + O2 --> CO2 + H2O
Now start by balancing the carbon atoms:
six carbons on the left so you need 6 on the right.
C6H12 + O2 ---> 6 CO2 + H2O
Next balance the hydrogen atoms:
12 on the left, so you need 12 on the right.
C6H12 + O2 --> 6CO2 + 6H2O
Now count the number of oxygen on the right = 12 + 6= 18
Divide the number on the right by 2 to get the number needed on the left. 18/2 = 9
