Answer:
7.13mL
Explanation:
P₁V₁T₁ = P₂V₂T₂
P₁ = 3atm , V₁ = 2.1 mL , T₁ = 273 + 4 =277K
P₂ = 0.95atm , V₂ = ? , T₂ = 273 + 25 =298K
V₂ = P₁V₁T₂ / P₂T₁
V₂ = (3atm)(2.1 mL )(298K) / (0.95atm)(277K)
V₂ = 7.13mL
Answer:
10 cm
Explanation:
Được
Tần số = 50 hertz
Khoảng cách đã đi = 25 m
Thời gian đi quãng đường 25 m = 5 giây
Tốc độ của sóng = 25/5 = 5 mét trên giây
Như chúng ta biết
Bước sóng = Vận tốc / tần số
Bước sóng = 5 mét trên giây / 50 trên giây
Bước sóng = 0,1 m = 10 cm
The weight is the force of gravity acting on the object. So assuming it’s on earth, 12(9.81) also, F(weight in Newtons)=mass( in kg)acceleration (due to gravity)
Answer:
Explanation:
"The thermal energy moving from her coffee to the tongue" represent the heat.
Here coffee is at high temperature while tongue is at low temperature, when Ixchelt tongue make contact with coffee then thermal energy of coffee is absorbed by tongue and tongue gets burned.
As heat always from high Potential to low that is why heat is absorbed by tongue.
The answer is directed northward. The acceleration will be negative, since the car is decelerating. Thus the power that is slowing it down must be performing in the opposite direction to that which the car is traveling. Or in other words, when speed is lessening, acceleration is in the opposed direction to velocity. The change is CONTRASTING the velocity and so it slows it down.
