Explanation:
distance covered in the first part of journey : 120×14 = 1680km
distance covered in second part of journey :
90×10 = 900 km
total distance traveled : 1680+900 = 2580km.
total time taken to complete the journey : 14+10= 24 hrs.
therefore, the average speed of the journey = 2580km/24hr = 107.5 km/h.
hope this helps you.
Answer:
A. 0.204203928 m
b. 0.1443939822
Explanation:
Givens:
Volume (V) = 160 m^3
velocity 1 (v1) = 3.00 m/s
velocity 2 (v2) = 6.00 m/s
Time (t) = 21.3 minutes = 1278 seconds
Side length = ?
V = A*v*t
A = s^2
V = s^2*v*t
s= 
A.
s = = 
= 0.204203928 m
B.
s = = 
= 0.1443939822 m
I hope this helped!! Have a good day.
Main answer- the velocity of 2.2kg ball is 12.566m/s
supporting answer- In circular motion the velocity is termed as angular velocity
Angular velocity represents the rate of variation of an object's position angle with respect to time.
W =theta/ time
W = length of the arc/ radius of circle × time
body of the answer-2πr/r×t =2π/t
2×π/ 0.5 = 12.566 m/s
final answer- hence the velocity of ball is revolving is 12.566 m/s

Answer:
Fb = 941.76 [N]
Explanation:
La fuerza de flotacion se define como el producto de la densidad del liquido por la aceleración gravitacional y por el volumen desplazado
Fb = Ro*g*V
donde:
Fb = fuerza de flotacion [N] (unidades del Newtons)
Ro = densidad del liquido = 1000 [kg/m³]
g = aceleracion gravitacional = 9.81 [m/s²]
V = volumen desplazado = 0.096 [m³]
Reemplazando:
Fb = 1000*9.81*0.096
Fb = 941.76 [N]
