Answer:
Heat makes the particles in a solid vibrate faster, giving them more kinetic energy. Faster-vibrating particles bump into one another more often and hit each other harder. ... When a sample of solid, liquid, or gas matter cools down, it contracts. When matter cools down, its particles lose kinetic energy.
Answer:
13.14
Step-by-step explanation:
sin 37.5 deg = 8/x
x = 8/sin 37.5 deg
x = 13.14
(I was thinking about it as a right angled triangle although the qn did not specify but idt you can solve it by using sine / cosine rule so TOA CAH SOH may be the only one and the most direct method to solve it)
So we want to know how many beads it takes to make a bracelet and a necklace if we have 192 beads and that we need 5 times more beads for the necklace. Let's say the number of beads we need for the necklace is n and the number of beads for the bracelet is b. We know that n + b = 192. Next we also know that 5b=n. When we plug that into our equation we get: 5b + b= 192 or:6b=192. so b=192/6=32. Now we know that the number of beads for the bracelet is 32. To get the number of beads for the necklace we simply plug in b=32 into 5b=n and we get 5*32=n so the number of beads to make a necklace is n=160.
