Answer:
The answer is 13 however make sure if they ask for a certain measurement like meter answer it by saying 13 meters.
Explanation:
This basically turns into basic algebra if you know the formula for work. The formula for work is W=F*d
Here are the variables that you know 650J=50N*d so you need d.
All you do is divide 650J by 50N and you get a total of 13 (meters since I don't know what they want you to put it in).
The kinetic energy of an object is given by:
where m is the mass of the object and v its velocity.
The car in this problem has a mass of m=600 kg and a velocity of v=10 m/s, therefore if we put these numbers into the equation, we find the kinetic energy of the car:
Answer:
The answer is D.
Explanation:
The Law of Conservation of mass states that matter is not created nor destroyed in a chemical reaction.
Answer:
<em>529.2N </em>
Explanation:
Given parameters:
Mass of the object = 54kg
Unknown:
Gravitational force acting on the mass = ?
Solution:
To solve this problem, the gravitational force acting on this body is tantamount to the weight of the object.
So;
Weight = mg
m is the mass
g is the acceleration due to gravity
Now;
Weight = 54 x 9.8 = <em>529.2N </em>
The gravitational force acting on the object is <em>529.2N </em>
Answer:
Explanation:
When water droplet condenses on the outer wall of glass of ice , it releases heat equal to mass x latent heat of condensation of water . This heat reaches the ice melting inside glass . Due to this heat , the melting process is accelerated .
Hence the process of melting gets accelerated when water droplet condenses on the outer wall of glass containing mixture of ice and water .
