An object that's moving doesn't necessarily change its speed or acceleration. Also, the force applied to it doesn't need to change ... in fact, a moving object doesn't need ANY force applied to it in order to keep moving.
But any moving object WILL have a change in its position ... THAT's how you know it's moving, and that's WHY you say "It's moving !". (choice-B)
Answer:
See below ~
Explanation:
An object will sink in water when its density is greater than that of water, which is 1 g/cm³.
Volume of the box is <u>1331 cm³</u>. (11³)
Maximum mass of sand will be 1331 g. [because 1331/1331 = 1 g/cm³]
- Volume of sand = Mass of sand / Density of sand
- Volume (sand) = 1331/3.5
- Volume (sand) = 380.29 cm³
If the volume of sand is <u>greater than 380.29 cm³</u>, the box will sink in water.
Nearly 14 billion years, according to astronomers. Happy to help!
Answer:
Required KVP = 86 KVP (Approx)
Explanation:
Given:
Current KVP = 75 KVP
Find:
KVP required to double exposure
Computation:
According to 15% rule of KVP,
15% change increse in KVP required to get double exposure.
So,
Required KVP = Current KVP + Current KVP(15%)
Required KVP = 75 KVP + 75 (15%)
Required KVP = 75 KVP + 11.25 KVP
Required KVP = 86.25 KVP
Required KVP = 86 KVP (Approx)
