The Top Thrill Dragster, a rollercoaster at Cedar Point in Ohio, soars through the air at 176ft/sec. How fast is this in mph?

Answers

Answer 1

Answer:

The rollercoaster has a speed of 176 ft/sec. This can be converted to miles per hour. The speed is equivalent to 120 mph.

What is speed ?

Speed is a physical quantity measuring the distance travelled by an object per unit time. Speed is a scalar quantity. The rate of speed is called velocity.

The speed can be expressed in different units. such as m/s, km/h, ft./s miles per hour etc. These units can be interconverted using specific relations.

One ft/s = 0.682 mph

then, 176 ft./s = 0.682 × 176 = 120 mph.

Therefore, the speed of the roller coaster is 120 mph.

Which component is required for the activation of some enzymes?a) Presence of a co-factor
b) Basic pH levels in the substrate
c) Higher enzyme concentration
d) Lower temperature in the substrate

Answers

The correct answer is option A.

Presence of a co-factor is required for the activation of some enzymes. Co-factors are generally metal ions or small molecules (non-protein).Co-factors helps enzymes bind substrate tightly. For example, NAD⁺/NADH is a co-factor which is required for the activation of the enzyme dehydrogenase. NAD⁺ is the oxidized form and NADH is the reduced form.

The best answer is letter A.
The main factors that change the speed of enzymatic reactions are temperature, pH and substrate concentration (quantity). There are enzymes that need other associated molecules to work. These molecules are called enzyme co-factors. They can be organic ions like mineral salts.

A certain reaction has an activation energy of 66.41 kJ/mol. At what Kelvin temperature will the reaction proceed 3.00 times faster than it did at 293 K?

Answers

Answer : The temperature will be, 392.462 K

Explanation :

According to the Arrhenius equation,

$K=A* e^{(-Ea)/(RT)}$

or,

$\log ((K_2)/(K_1))=(Ea)/(2.303* R)[(1)/(T_1)-(1)/(T_2)]$

where,

$K_1$ = rate constant at $T_1$ = $K_1$

$K_2$ = rate constant at $T_2$ = $3K_1$

$Ea$ = activation energy for the reaction = 66.41 kJ/mole = 66410 J/mole

R = gas constant = 8.314 J/mole.K

$T_1$ = initial temperature = 293 K

$T_2$ = final temperature = ?

Now put all the given values in this formula, we get:

$\log ((3K_1)/(K_1))=(66410J/mole)/(2.303* 8.314J/mole.K)[(1)/(293K)-(1)/(T_2)]$

$T_2=392.462K$

Therefore, the temperature will be, 392.462 K

An isotope remains unchanged by the emission of a gamma ray, which is a(n) __________.

Answers

Answer:

The answer to your question is photon. An isotope remains unchanged by the emission of a gamma ray, which is a (an) photon123. A photon is a particle of light or electromagnetic radiation that has no mass and no electric charge4. A gamma ray is a type of photon that has the highest energy and frequency in the electromagnetic spectrum4. Gamma rays are emitted by the nuclei of some radioactive atoms when they undergo a nuclear rearrangement or decay4. Gamma ray emission causes no change in the number of particles in the nucleus, meaning both the atomic number and mass number remain the same23. Therefore, an isotope does not change its identity or mass when it emits a gamma ray, but only releases some excess energy as a photon. I hope this answer helps you understand the concept of gamma ray emission better.
