The answer to your question is A, The force that holds together elements in a compound.
<u>TRANSISTOR:</u>
The future of transistors based on the ongoing researches suggests that, it would be based on nano technology. This technology is itself still under development and the case is similar in the case of transistors too.
Transistors due to their applications, especially its application as an amplifier has increased its usage and the dependability over them. The hard part often arises with the fabrication techniques which are being tested and developed as we speak in order to increase the efficiency of the transistors and also to reduce their physical size though, these would mean that, the design complications would be higher.
B: Sprinting. It is the best answer because it demonstrates speed better than the others
Answer:
<em>The volume of water is 3.5 cubic meter</em>
Explanation:
<u>Density
</u>
The density of a substance or material is the mass per unit volume. The density varies with temperature and pressure.
The formula to calculate the density of a substance of mass (m) and volume (V) is:
We are given the density of water as 
.It's required to find the volume of m=3,500 kg of water. Solving for V:
The volume of water is 3.5 cubic meter
Answer:
10 m/s
Explanation:
The potential energy of the roller coaster is converted to kinetic energy. According to law of transformation of energy, potential energy = kinetic energy.
mgh = ½mv².Take g as 10m/s².
150 * 10 * 50 = ½ * 150 * v².
7500 = 75v².
v² = 7500/75.
v = √100.
v= 10 m/s
