Answer:
a) Q = 80,000 cal
b) Q = 100,000 cal
c) Q = 540,000 cal
d) Q = 720,000 cal
Explanation:
a)1 kg from 0⁰ Ice to 0⁰ water, the heat produced is latent heat of fusion
= 1 * 80
= 80 kCal = 80,000 cal
b) 1 kg of O°C ice water to 1 kg of 100°C boiling water
Specific heat capacity, c = 1000cal/kg.C
c) 1 kg of 100°C boiling water to 1 kg of 100°C steam
Latent heat of vaporization is needed for this conversion
d) 1 kg of O°C ice to 1 kg of 100°C steam.
Q = 
Q = 80,000 + 100,000 + 540,000
Q = 720,000 cal
The mass on the spring is bouncing.
We would call it a wave-like motion, except that it all stays in the same place. But, just like a wave, moving from the highest position to the lowest position
is one-half of a full wiggle.
(The other half consists of moving from the lowest position back up to the
highest position, where it started from.
So, half of the wave-like motion takes 0.6 seconds.
A full cycle of the wave motion ... the actual period of the bounce,
is double that much time . . .
1.2 seconds.
Explanation:
Given:
Using Newton's universal law of gravitation, we can write
<u>The following statements are true about centripetal force
:</u>
- Without centripetal force, an object would continue in a straight
- line.
- Gravity can be a centripetal force, such as when it pulls a thrown
- baseball down to the ground.
- Friction can be a centripetal force, such as when it keeps a car on the road going around a curve.
Answer: Option A, C, and D
<u>Explanation:
</u>
Centripetal Force & Examples-
Centripetal force can be defined as the component of force that acts on an object in a curvilinear motion, directed towards the centre of axis of the circular path. This is the force responsible to pull an object in an inward direction and balance the pace on the path.
In the absence of the centripetal force, an object will either move in the direction of motion or on a straight path instead of moving inwards. It's also called as an "inward Force" as it tends to move the object towards the centre of the curved path.
As an example, a car moving on a circular road accelerates due to its constant change in direction since it's moving on a circular path. Now, the frictional force comes into picture that contributes its component as a centripetal force, pulling it towards the centre of the axis of the circular path.
Hence we can say that when a car turns on a circular path, friction force acts a centripetal force to maintain its motion and direction on the path. Talking about a baseball which is attracted by the gravitational force of the Earth and hence falls on the ground is clearly not the case of centripetal force as the path may not be circular every time and there is not axis of rotation.
Besides centripetal force, there is another force that acts on an object moving on a circular path but not in the inward direction. It is instead, equal and opposite of the centripetal force that draws the object away from the circular path of motion. Hence, it's called the "Outward force".
The ideal gas constant is a proportionality constant that is added to the ideal gas law to account for pressure (P), volume (V), moles of gas (n), and temperature (T) (R). R, the global gas constant, is 8.314 J/K-1 mol-1.
According to the Ideal Gas Law, a gas's pressure, volume, and temperature may all be compared based on its density or mole value.
The Ideal Gas Law has two fundamental formulas.
PV = nRT, PM = dRT.
P = Atmospheric Pressure
V = Liters of Volume
n = Present Gas Mole Number
R = 0.0821atmLmoL K, the Ideal Gas Law Constant.
T = Kelvin-degree temperature
M stands for Molar Mass of the Gas in grams Mol d for Gas Density in gL.
