The answer would be choice A)2H2O
Answer:
Final concentration M2 = 0.0472 M
Explanation:
Given:
Initial volume V1 = 10 ml
Initial concentration M1 = 1.18 M
Final volume V2 = 250 ml
Find:
Final concentration M2
Computation:
Using conservation of volume;
(Initial volume)(Initial concentration) = (Final volume)(Final concentration)
M1V1 = M2V2
(1.18)(10) = (Final concentration M2)(250)
(1.18)(10) / 250 = (Final concentration M2)
Final concentration M2 = 11.8 / 250
Final concentration M2 = 0.0472 M
Answer:
d. Epoxy
Explanation:
Adhesion or adhesive properties of a substance is the property that allows bonding of dissimilar materials if necessary. Adhesives may have high cohesive strength or a low cohesive strength.
PVC "glue" is usually a solvent for plastic components and these are different type of PVC glues. They function well on plastics.
HDPE - is known as High-density polyethylene or polyethylene high-density is a thermoplastic polymer in short it is what we know as plastic bags or nylon produced from the monomer ethylene. HDPE is not an adhesive
UHMWPE - is known as Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE). UHMWPE is not an adhesive.
An epoxy adhesive is a copolymer adhesive formed by mixing together a resin and a hardener. There are some special epoxies however don't require a hardener, but are activated by heat instead. Others epoxies hardening strength may degrade in under exposure to ultraviolet light or high heat. Adhesives such as epoxies have many different uses. Epoxy may be used on metal, glass, plastic, rubber, fiberglass and fiberglass-reinforced plastic (FRP).
Bakelite or polyoxybenzylmethylenglycolanhydride isn't an adhesive and it was the first plastic made from synthetic components.
Epoxy however has very strong adhesive properties because of the varieties of substances it can bring to together.
Answer:
Honey
Explanation:
It’s honey because the item that was dropped in it is almost at the top and that means there is something sticky or force there holding it back!
Answer:
43.868 J
Explanation:
Kinetic energy of a body is the amount of energy possessed by a moving body. The SI unit of kinetic energy is the joule (kg⋅m²⋅s⁻²).
According to classical mechanics, kinetic energy = 1/2 m·v²
Where, m= mass in kg and v= velocity in m/s
Given: m = 19.2 lb and v = 7.10 miles/h
Since, 1 lb= 0.453592 kg
∴ m = 19.2 lb = 19.2 × 0.453592 kg = 8.709 kg
Also, 1 mi = 1609.34 m and 1 h = 3600 sec
∴ v = 7.10 mi/h = 7.10 × 1609.34 m ÷ 3600 sec = 3.174 m/sec
Therefore, <u>kinetic energy of the goose</u> = 1/2 m·v² = 1/2 × (8.709 kg)× (3.174 m/sec)² = 43.868 J
