denis-greek [22]3 years ago
3 0

Answer:

Tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s

Explanation:

From the question above,

(1) tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s

Mometum = mass×velocity

Momentum = 270×0.5

Momentum = 135 kgm/s

(2) hare with a mass of 2.7 kg moving at a velocity of 7 m/s

Mementum = mass × velocity

Momentum = 2.7×7

Momentum = 18.9 kgm/s

(3) turtle with a mass of 91 kg moving at a velocity of 1.4 m/s

Momentum = mass × velocity

Momentum = 91×1.4

Momentum = 127.4 kgm/s

(4) roadrunner with a mass of 1.8 kg moving at a velocity of 6.7 m/s

Momentum = mass × velocity

Momentum = 1.8×6.7

Momentum = 12.06 kgm/s

From the above, the one with the greatest momentum is tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s

Hydrogen cyanide (HCN) is a product of combustion that:
bekas [8.4K]

b. is equally as toxic as carbon monoxide (CO).

Explanation:

Hydrogen Cyanide is a product of combustion that is equally as toxic as carbon monoxide CO.

The gas is a product of combustion in blast furnances, coke ovens, e.t.c

  • Just like carbon monoxide, they are blood agents that are toxic in the body
  • Prolonged exposure to hydrogen cyanide can lead to death eventually.
  • The gas is a able to produce cyanide ion that seriously impacts the process of cellular respiration and bringing it to a halt.
  • It is listed as one of the dangerous chemical weapons.

Capacitor C1 is initially charged to V1 and capacitor C2 is initially charged to V2. The capacitors are then connected to each o
o-na [289]

Answer:

<em>20.08 Volts</em>

Explanation:

<u>Parallel Connection of Capacitors</u>

The voltage across any two elements connected in parallel is the same. If the elements are capacitors, then each voltage is

\displaystyle V_1=\frac{Q_1}{C_1}

\displaystyle V_2=\frac{Q_2}{C_2}

They are both the same after connecting them, thus

\displaystyle \frac{Q_2}{C_2}=\frac{Q_1}{C_1}

Or, equivalently

\displaystyle Q_2=\frac{C_2Q_1}{C_1}

The total charge of both capacitors is

\displaystyle Q_t=Q_1\left(1+\frac{C_2}{C_1}\right)

We can compute the total charge by using the initial conditions where both capacitors were disconnected:

Q_t=V_{10}C_1+V_{20}C_2=25\cdot 24+13\cdot 11=743\ \mu C

Now we compute Q1 from the equation above

\displaystyle Q_1=\frac{Q_t}{\left(1+\frac{C_2}{C_1}\right)}=\frac{743}{\left(1+\frac{13}{24}\right)}=481.95\ \mu C

The final voltage of any of the capacitors is

\displaystyle V_1=V_2=\frac{481.95}{24}=20.08\ V

In the following lever system, what is the clockwise torque? 18 Nm 240 Nm 360 Nm 480 Nm
MaRussiya [10]

Answer:

240 Nm

Explanation:

The clockwise torque is the torque determined only by the force that makes the lever rotating clockwise: therefore, the force of 80 N on the right.

The torque produced by this force is given by:

\tau = F d

where

F is the magnitude of the force

d is the arm

For the force of 80 N on the right,

F = 80 N

d = 3 m (distance from the pivot)

So, the clockwise moment is

\tau = (80)(3)=240 Nm
