Answer:
Pressure (P) is the amount of force applied perpendicular to the surface of an object per unit area. The SI unit of pressure is the pascal (Pa), which is equivalent to N/
(newtons per meter squared).
Answer: hello the terms are missing but I have provided the answer ( the terms and matched them properly
answer :
- P WAVES
- S WAVES
- L WAVES
- R WAVES
Explanation:
This body wave is a compressional wave : P WAVES
This body wave is a shear wave : S WAVES
This surface wave moves from side to side : L WAVES
This surface wave moves up and down. : R WAVES
A body wave is a type of wave that passes through the interior of the earth and they are classified as ; P and S waves while surface waves are seismic waves that travel near the earth's surface
Answer:
v = 3(m1 - 2m2)/(m1 + m2)
Explanation:
Parameters given:
Velocity of first toy car with mass m1, u1 = 3 m/s (taking the right direction as the positive axis)
Velocity of second toy car with mass m2, u2 = -6 m/s (taking the left direction as the negative x axis)
Using conservation of momentum principle:
Total initial momentum = Total final momentum
m1*u1 + m2*u2 = m1*v1 + m2*v2
Since they stick together after collision, they have the same final velocity.
m1*3 + (m2 * -6) = m1*v + m2*v
3m1 - 6m2 = (m1 + m2)v
v = (3m1 - 6m2) / (m1 + m2)
v = 3(m1 - 2m2) / (m1 + m2)
Answer:
Tiempo, t = 6.11 segundos.
Explanation:
Dados los siguientes datos;
Distancia = 140 m
Aceleración = 7,5 m/s²
Dado que el objeto partió del reposo, su velocidad inicial es igual a 0 m/s.
Para encontrar el tiempo, usaríamos la segunda ecuación de movimiento;
S = ut + ½at²
Dónde;
S representa el desplazamiento o la altura medida en metros.
u representa la velocidad inicial medida en metros por segundo.
t representa el tiempo medido en segundos.
a representa la aceleración medida en metros por segundo cuadrado.
Sustituyendo en la ecuación, tenemos;
140 = 0*t + ½*7.5*t²
140 = 0 + 3.75t²
140 = 3.75t²
Dividiendo ambos lados por 3,75, tenemos;
t² = 140/3.75
t = √37.33
Tiempo, t = 6.11 segundos
