Actually, the best way to put it would be if the current is too large or too small.
Fuses and circuit breakers are both devices that "break" if the current flowing through them is too large.
A fuse is usually a thin piece of wire that will melt and break the circuit if too large a current flows through it. The thicker the fuse wire, the more the current needed to melt it and the higher the "rating" of the fuse. The function of the fuse is to protect the wiring and the equipment.
A circuit breaker is an electronic circuit that will switch off the current if it is too great. A circuit breaker is designed to operate much more quicker than a fuse and so the damage is less because the current is switched off in a much shorter time.
Answer:
#_time = 7.5 10⁴ s
Explanation:
In order for the astronaut to be younger than the people on earth, it follows that the speed of light has a constant speed in vacuum (c = 3 108 m / s), therefore with the expressions of special relativity we have.
t =
where t_p is the person's own time in an immobile reference frame,
let's calculate
we assume that the speed of the space station is constant
t_ = 0.99998666657 s
therefore the time change is
Δt = t - t_p
Δt = 1 - 0.9998666657
Δt = 1.3333 10⁻⁵ s
this is the delay in each second, therefore we can use a direct rule of proportions. If Δt was delayed every second, how much second (#_time) is needed for a total delay of Δt = 1 s
#_time = 1 / Δt
#_time =
#_time = 7.5 10⁴ s
Answer:
0.47922 kgm/s and will move right to left
Explanation:
= Mass of broccoli-tomato-pickle-onion-mushroom pizza = 235 g
= Mass of veggieburger-on-a-bun = 351 g
= Velocity of broccoli-tomato-pickle-onion-mushroom pizza = 1.65 m/s
= Velocty of veggieburger-on-a-bun = -2.47 m/s
Left to right is considered positive direction and the opposite is negative direction
Net momentum is
The combined dish has a momentum of 0.47922 kgm/s and will move right to left
2Na + Cl₂ → 2NaCl
Explanation:
The reaction of sodium metal with chlorine gas to produce sodium chloride is a typical example of synthesis reaction.
Combination or synthesis involves the formation of a single product from two or more reactants.
A + B ⇒ C
In this kind of chemical reaction, a single product is formed or some compounds by the union of elements is notable.
The driving force for this category of chemical reaction is the large and negative heat of formation of the product.
