i believe it would be the same because time doesn't matter when calculating total work done.
Work=FxD
F=force
D=distance
The gold was heated at rates too fast for the electrons absorbing the light energy to collide with surrounding atoms and lose energy.
The final position of the car is 385 m.
Explanation:
We know the formula :
s =

where,
s = distance
u = initial velocity = 5.1 m/s
t = time taken = 14 sec
a = acceleration = 3.2 m/
Solving:
s = 5.1* 14 +
* 3.2 * 
∴ s = 385 m
Hence the final position of the car is 385 m.
The velocity of the stuntman, once he has left the cannon is 5 m/s.
The right option is O A. 5 m/s
The Kinetic energy of the stuntman is equal to the elastic potential energy of the spring.
<h3 /><h3>Velocity: </h3>
This is the ratio of displacement to time. The S.I unit of Velocity is m/s. The velocity of the stuntman can be calculated using the formula below.
⇒ Formula:
- mv²/2 = ke²/2
- mv² = ke².................. Equation 1
⇒ Where:
- m = mass of the stuntman
- v = velocity of the stuntman
- k = force constant of the spring
- e = compression of the spring
⇒ Make v the subject of the equation
- v = √(ke²/m)................. Equation 2
From the question,
⇒ Given:
- m = 48 kg
- k = 75 N/m
- e = 4 m
⇒ Substitute these values into equation 2
- v = √[(75×4²)/48]
- v = √25
- v = 5 m/s.
Hence, The velocity of the stuntman, once he has left the cannon is 5 m/s.
The right option is O A. 5 m/s

Answer:
Sodium - D) Malleable, soft, and shiny
Sodium is an alkalyne metals that is why they are soft and sodium can cut by knife.
Silicon - C) Has properties of both metals and nonmetals
As we know that those materials have both nonmetals and metals properties are known as metaloid.
Bromine - A) Highly reactive gas
All halogens are so reactive .Because they are high electro negative element.Bromine(Br) is a halogen element.
Argon - B) Nonreactive gas
All noble gases are stable that is why they are not reactive with ant other element.So we can say that noble gas are Nonreactive gas.Argon(Ar) is noble gas.
