Answer:
The time it will take to cook three hot dogs simultaneously is 2.5 minutes
Explanation:
Here we have, the Energy of electric heating given by Joule heating that is;
P = IV = 120×10 = 1200 J/s = 1.2 kJ/s
Since the energy required to cook one hotdog = 60.0 kJ we have
Energy required to cook three hot dogs = 3 × 60.0 kJ = 180.0 kJ
Therefore, the time required to cook the three hot dogs is
(180.0 kJ)/(1.2 kJ/s) = 150 s
The time it takes to cook three hot dogs simultaneously is
150 seconds or 150/60 minutes which is 2 minutes 30 seconds or 2.5 minutes
The two spheres have opposite charges.
<h3 /><h3 /><h3>What are types charge?</h3>
- A charge can be negatively charged or positively charged.
- When two charges have opposite signs, that is positive and negative signs, the two charges will attract each other.
- When the two charges have the same sign, it causes repulsion.
When a positive charge points downwards ↓ and the negative charge points upwards ↑, this causes attraction and shows that the two charges are different.
Thus, we can conclude that the two spheres have opposite charges.

Answer:
4.617 s
Explanation:
The speed of 60 mi/h can be converted to m/s:
(60 mi/h) × (1609.344 m/mi) × (1 h)/(3600 s) = 26.8244 m/s
The relationship between speed and acceleration is ...
v = at
t = v/a = (26.8244 m/s)/(5.81 m/s²) ≈ 4.617 s
It will take the car 4.617 seconds to reach 60 mi/h starting from rest.
Answer:
kinetic energy increases with the energy which causes the particles to move faster resulting in increases collision rates and rate of diffusion.
