Cells are grouped together to carry out specific functions. A group of cells that work together form a tissue. Your body has four main types of tissues, as do the bodies of other animals. These tissues make up all structures and contents of your body.
Answer:
v = 158 m / s
Explanation:
In this kinematic problem they give us the acceleration of the body, the position and speed of the initial moment, let's use the definition of acceleration
a = dv / dt
dv = a dt
We integrate
∫ d v = ∫ (2t + 1) dt
v = 2 (2t²) + 1t
We evaluate between the initial time t = 0 that has speed (vo) 8 m/s and the final time t with speed v
v -8 = 4t2 + t
We already have the velocity formula as a function of time, let's calculate for t = 6 s
v = 8 + 4 6² +6
v = 158 m / s
Answer:
is the distance from the obstacle of reflection.
wavelength 
Explanation:
Given that:
- frequency of sound,
- time taken for the echo to be heard,
- speed of sound,
We know,
<em>During an echo the sound travels the same distance back and forth.</em>
is the distance from the obstacle of reflection.
<u>Now the wavelength of sound waves:</u>
Answer:
50N
Explanation:
A1 (area of the smaller piston) = 20cm² = 0.2m²
F1 (force acting on the smaller piston) = 10N
F2 (force acting on the larger piston) =?
A2 (area of the larger piston) = 100cm² = 1m²
F1 / A1 = F2 / A2
F2 = (F1*A2) / A1
F2 = (10*1) / 0.2
F2 = 50N
