How far away from Ball X will Ball Y hit the ground?
Answers
Answer: The distance between Ball X and Ball Y is 4.0 meters
Explanation:
First we have to use the information we have from Ball Y to find time as well as it’s distance.
Ball Y’s Given:
Vx=8.0m/s
ax=0m/s^2
x=?
y=1.25m
ay=-10m/s^2
To find the time, use the equation t=(2y/g)^1/2.
t=(2(1.25)/10)^1/2
t=(2.5/10)^1/2
t=(0.25)^1/2
t=0.5s
Now we have to calculate how far away Ball Y fell from the base of the cliff. To do this use the equation x=(Vx)(t) and plug in the values.
x=(8.0m/s)(0.5s)
x=4.0m
Because Ball X is dropped from the cliff, we can conclude that the ball is 0meters away from the cliff. With this in mind, we can assume that the distance between Ball X and Ball Y is 4.0m.
Total Distance = Ball Y - Ball X
Total Distance = 4.0 m - 0 m
Total Distance = 4.0 m

Answer:
Explanation:
The sensor contains an LDR which has a resistance of 10kohlms in daylight and 100kohlms in the dark.
If the resistor in the circuit is 1 megaohlm, the total resistance in daylight and darkness will be 1.01 megaohms and 1.1 megaohlms.
The percentage difference = (1.1-1.01)/1.1*100% = 8.18%
If the resistor in the circuit is 25 kohlm, the total resistance in daylight and darkness will be 35 kohms and 125 kohlms.
The percentage difference = (125-35)/125*100% = 72%
With the input p.d to the sensing circuit fixed at 12 v, the sensing current will change according to the total resistance. A 72% difference is much more detectable. So the 25 kohm resistor is the better choice.
Answer:
Explanation:
V=IR
I=12/(R of resistor + R of LDR)
R of LDR = 10kohm in light and = 100kohm in dark
R1 = 25kohm
R2 = 1Mohm
solve 4 current
light dark
R1 12/(25+10)=0.343mA 12/(25+100)=0.096mA
R2 12/(1000+10)=0.012mA 12/(1000+100)=0.011mA
so R1 is better as its easier 2 tell its light or dark

Answer : The SI unit to measure length is "meter".
Explanation :
SI unit means the international system of units. There are some fundamental units and some of the units are derived from fundamental units.
The SI units of some quantities are as follows :
- Mass : The SI unit of mass is Kilogram or Kg.
- Volume : The SI unit of volume of liter.
- Length : The SI unit of length is meter.
- Temperature : The SI unit of temperature is kelvin.
Hence, the correct option is (b) " meter ".
Answer:
Option c: Meter.
Explanation:
The meter is the unit of length in the international system of units. That system establishes standard measure at an international level for the following units:
- Meter (m)
- Seconds (s)
- Kilograms (Kg)
- Ampere (A)
- Kelvin (K)
- Mol (mol)
The meter is defined as the distance that light travels in vacuum in ratio of of a second.

Answers
There are three types of heat transfer or heat propagation; conduction, convection and radiation. Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.
Conduction is the heat transfer by contact, immediate contact.
Convection is the transfer of heat through air and water.
Radiation is the transfer of heat regardless of the presence of atoms or particles.
Radiation is the answer.
