Desmond is a scientist working with a culture of bacteria. 2500 bacteria in a petri dish are growing at a rate of 3% per second.

Which expression represents the number of bacteria in the petri dish after t seconds? options : p=2500e.03t p=2500⋅(1.03)t p=2500.03t p=2500e1.03t

Answer:

P = 2500 (1.03)^t

Explanation:

The bacteria grow exponentially. The initial number is 2500, and the growth rate is 3%, so the expression is:

P = 2500 (1.03)^t

A rocket starting from its launch pad is subjected to a uniform acceleration of 100 meters/second2. Determine the time needed to
balandron [24]
The velocity is the integral of acceleration.  If acceleration is 100 m/s^2 then velocity is:

v= \int\limits^{}_{}100 \, dt=100t

So to know the velocity at any time, t, we just put t in seconds into this equation.  To know at what time we get to a certain velocity, we set this equation equal to that velocity and solve for t:

100t = 1000 \\  \\  t= \frac{1000}{100} =10s

I think it would be yes because the drum is submerged in water and the water would slow the sound waves, making the sound softer. Right?

A sample of oxygen gas at 25.0°c has its pressure tripled while its volume is halved. What is the final temperature of the gas?
Marat540 [252]

Answer:

447 K

Explanation:

25 C = 25 + 273 = 298 K

Assuming ideal gas, we can apply the ideal gas law

\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}

T_2 = T_1\frac{P_2}{P_1}\frac{V_2}{V_1}

Since pressure is tripled, then P_2 / P_1 = 3. Volume is halved, then V_2 / V_1 = 0.5

T_2 = 298*3*0.5 = 447 K
