Answer:

Cesium has smallest ionization energy.

Explanation:

Ionization energy is the energy that an atom at ground state must be absorb to release an electron to form a cation. for eg.

H ⇒ $H^{+} + e^{-}$

The unit of ionization energy is $\frac{KJ}{mol}$ .

The ionization energy is minimum for cesium & maximum for fluorine.

Ionization energy depends upon the radius of atom. cesium has smallest radius so it has low Ionization energy.

Therefore the cesium has smallest ionization energy.

How long is the racetrack if it takes a racecar 3.4 s travelling at 75 m/s to finish?

RSB [31]

Answer:

255 metres

Explanation:

The answer to thi question is actually quite simple. Since the car goes for 3.4 seconds, and it goes 75 metres every second, the answer is just 3.4 multiplied by 75 Metres.

A flywheel with radius of 0.300 m starts from rest and accelerates with a constant angular acceleration of 0.400 rad/s2.For a po

oksian1 [2.3K]

Answer:

$0.12\ m/s^2$

Explanation:

Given that,

The radius of a flywheel, r = 0.3 m

Angular acceleration of a flywheel, $\alpha =0.4\ rad/s^2$

We need to find the magnitude of the tangential acceleration after 2.00 s of acceleration.

The relation between the tangential and angular acceleration is given by :

$a_t=r\alpha \\\\a_t=0.3\times 0.4\\\\a_t=0.12\ m/s^2$

So, the required magnitude of tangential acceleration is $0.12\ m/s^2$ .

What is the difference between longitudinal and transverse waves?

Greeley [361]

Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave. ... Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.

8. An airplane is flying at 200 m/s when it touches the ground at the airport. It has a constant negative acceleration, and slow

Temka [501]

Answer:

Explanation:

Given

Initial velocity u = 200m/s

Final velocity = 4m/s

Distance S = 4000m

Required

Acceleration

Substitute the given parameters into the formula

v² = u²+2as

4² = 200²+2a(4000)

16 = 40000+8000a

8000a = 16-40000

8000a = -39,984

a = - 39,984/8000

a = -4.998m/s²

Hence the acceleration is -4.998m/s²
