Answer: FITT↓

Frequency: refers to the frequency of exercise undertaken or how often you exercise.

Intensity: refers to the intensity of exercise undertaken or how hard you exercise.

Time: refers to the time you spend exercising or how long you exercise for.

Type: refers to the type of exercise undertaken or what kind of exercise you do.

Explanation:

Hope this helps

A beam of ultraviolet radiation, with frequency

andreyandreev [35.5K]

To develop this problem, we will apply Einstein's relationship which is in charge of the work done with the kinetic energy of the body versus the total energy of the system.

The energy can be calculated as

$E = hf$

Here,

h = Planck's Constant

f = Frequency

Our values are given as,

$f = 2.78*10^{15} Hz ,$

$W = 3.80 eV$

Therefore the Energy is

$E = hf$

$E = 6.625*10^{-34}J\cdot s(2.78*10^{15}Hz)$

$E = 1.84*10^{-18}J \rightarrow 1 J = 6.242*10^{18}eV$

Then,

$E = 11.48eV$

Applying the Einstein Relation we have that

$E = W+KE$

$KE = E -W$

$KE = 11.48eV-3.80 eV$

$KE = 7.68eV$

Therefore the maximum kinetic energy for an electron dislodged fromthe surface by the radiation is 7.68eV

You are driving home from school steadily at for 180 km. It then begins to rain and you slow to You arrive home after driving 4.

nata0808 [166]

Answer:

Explanation:

Question is incomplete

Assuming the question you have asked is

You are driving home from school steadily at 95 km/h for 180 km. It then begins to rain and you slow to 65 km/h. You arrive home after driving 4.5 h.

given,

speed of 95 km/h for 180 km

due to rain

speed is reduced to 65 km/h

distance traveled in 4.5 hour

time taken to travel 180 km

d = s x t

$t = \dfrac{180}{95}$

t = 1.9 hr

distance traveled in time, t' = 4.5-1.9 = 2.6 hr

Speed of vehicle = 65 Km/h

d' = s x t'

d' = 65 x 2.6

d'= 169 Km

total distance your hometown from school

D = d + d'

D = 180 + 169

D = 349 Km

A force of 12,000 n is exerted on a piston that has an area of 0. 020 m 2. What is the area of a second piston that exerts a for

Stolb23 [73]

The area of a second piston that exerts a force of 24,000 N is 0.04 $m^{2}$ .

Gravitational force is measured in newtons. Utilizing the physics formula pressure = force/area, you can compute pressure if you know the value of a force. Both pounds per square inch (psi) and newtons per square meter (N/m2) are acceptable units of measurement for this pressure.

Given force 1 = 12,000 N

The pressure which has produced a force of 12,000 N at the piston 1 = Force/ area

= 12,000N / 0.020 $m^{2}$

= 6,00,000 N/ $m^{2}$

Now force at piston 1 must be equal to force at piston 2. thus, force at piston 2 is given by:

Force at piston 2 = pressure × area

24,000 N = 6,00,000 × area

area = 0.04 $m^{2}$
