Answer:
Explanation:
(A) water proofing is designed to keep out soil moisture and liquid water through a concrete structure while damp proofing is a coating on the exterior of a structure so as to stop the transference of ground moisture through concrete.
(B) Water proofing is more appropriate when the water table of the region is higher and there is higher rainfall, it is also more appropriate when there is a presence of hydro-static pressure.
while
Damp proofing is more preferable when there is a drier climate, there is a lower water table, also when there is a well drained soil and also good gravity drain.
Answer:
he correct answer is 7 3 10⁻⁹ s
Explanation:
The speed of light is constant, so we can use the uniform motion ratios
v = x / t
t = x / v
let's calculate
t = 1 / 2.9972 10⁸8
t = 3.336 10⁻⁹ s
the correct answer is 7 3 10⁻⁹ s

De la información dada:
La distancia total recorrida= 650 m + 500 m
La distancia total recorrida= 1150 m
La magnitud se puede calcular utilizando el teorema de Pitágoras.
a² = b² + c²
a² = 500² + 650²
a² = 250000 + 422500
a² = 672500
a =
a = 820 m
La dirección del desplazamiento resultante es la dirección noreste desde el punto de partida.
The length of the string must vary, while the angle and acceleration are constant
