The frequency of the wave is 5 Hz and the amplitude is 0.002 m.
<h3>What is wave?</h3>
A wave is a disturbance in a medium that carries energy without a net movement of particles. In general, waves are classified into two types as Longitudinal and Transverse.
Given is a wave as shown in the image.
[A] -
The time period of wave [T] = 0.2 s
Frequency [v] = 1/T = 1/0.2 = 10/2 = 5 Hz
[B] -
Amplitude = maximum vertical displacement = 2mm = 0.002 m
Therefore, the frequency of the wave is 5 Hz and the amplitude is 0.002 m.

Answer:
-2000 N
Explanation:
First of all, let's calculate the acceleration of the car:
where
v = 0 is the final velocity of the car
u = 10 m/s is the initial velocity of the car
t = 5 s is the time elapsed
Substituting,
where the negative sign means it is a deceleration.
Now we can calculate the average braking force:
where m=1000 kg is the mass of the car. Substituting,
and the negative sign means the force is opposite to the direction of motion of the car.
Answer:
Option (1) f = 1
Explanation:
Formula for Frequency (F) = 1/t where t = Time in seconds.
F = 1/1
F = 1 hz ( hz or hertz is the unit for Frequency ).
Answer:
false, they are more reliable.

Answer:
Rate of energy loss by radiation is 28.31 Watt
Explanation:
Given that;
m = 30 kg
power p = 12 W
emissivity e = 0.97
Surface Area A = 0.56 m²
outside of the penguin's body T = −22°C
surroundings Temperature Ts = -38°C
the rate of energy loss by radiation = ?
Now, using Stefan-Boltzmann law;
P = σeA [ T⁴ - Ts⁴ ]
Stefan's constant σ = 5.67 × 10⁻⁸
so we substitute
P = 5.67 × 10⁻⁸ × 0.97 × 0.56 [ (-22 + 273 k)⁴ - (-38 + 273 k )⁴]
= 3.079944 × 10⁻⁸ [ 919325376]
= 28.31 Watt
the rate of energy loss by radiation is 28.31 Watt
