Answer:
The value is 
Explanation:
From the question we are told that
The mass of the ice cube is 
The temperature of the ice cube is 
The mass of the copper cube is 
The final temperature of both substance is 
Generally form the law of thermal energy conservation,
The heat lost by the copper cube = heat gained by the ice cube
Generally the heat lost by the copper cube is mathematically represented as
![Q = m_c * c_c * [T_c - T_f ]](https://tex.z-dn.net/?f=Q%20%3D%20%20m_c%20%20%2A%20%20c_c%20%2A%20%20%5BT_c%20%20-%20%20T_f%20%5D)
The specific heat of copper is 
Generally the heat gained by the ice cube is mathematically represented as
Here L is the latent heat of fusion of the ice with value 
So
=> 
So
![2505 = 0.540 * 385 * [T_c - 0 ]](https://tex.z-dn.net/?f=2505%20%20%3D%20%200.540%20%20%2A%20%20385%20%2A%20%20%5BT_c%20%20-%200%20%5D)
=>
Answer:
They would land at the same time
Explanation:
They would land at the same exact time.
As weird, impossible and unbelievable as it appears. When in a vacuum, every weight, body and material when released from the same height would land on the ground at the same time. This also means that like in the question, a feather and a ball would land at the same time. And just for illustrations as well, a feather and a car would land at the same time as well.
Answer:
The appropriate solution is:
(a) 
(b) 
(c) 
Explanation:
According to the question, the value is:
Power of bulb,
= 60 W
Distance,
= 1.0 mm
Now,
(a)
⇒ 
On applying cross-multiplication, we get
⇒ 
⇒ 
⇒ 
(b)
As we know,
⇒ 
By putting the values, we get
⇒ 
(c)
⇒ 
⇒ 
⇒ 
Answer:
The answer to your question is 1800 Pa
Explanation:
Data
Weight = 2700 N
Area = 1.5 m²
Pressure = ?
Formula
Pressure = Force / Area
The Pressure is defined as the force exerted per unit area.
-Substitution
Pressure = 2700 / 1.5
-Result
Pressure = 1800 Pa
The units of pressure are Pascals (Pa)
