c: a combination of longitudinal and transverse

Explanation:

Surface waves are a combination of longitudinal and transverse waves. These waves causes destruction after an earthquake on the ground surface.

The surface waves are both rayleigh and love waves.
Rayleigh waves and love waves are responsible for the destruction caused by an earthquake.
They both have a unique characteristic of being propagated longitudinally and transversely away from their source.
The spread compressional disturbance and undulating ones at the same time on the earth surface.
These waves are seismic waves.

Subtracting a negative number follows the same process as a positive number

Sav [38]

This would be true!

When you subtract a positive number, it goes to the left of the number line. When you subtract a negative number, it goes to the left of the number line.

The thing that confuses most people is that the first number (when negative) continues to increase as a negative. It follows the same process, just different signs.

I hope this helps!

A particle's position along the x-axis is described by: x(t)=A t + B t2

ki77a [65]

Answer:

a)V = 25.1 m/s

b)V = 4.226 m/s

Explanation:

Given that

x(t)=A t + B t²

A = -4.3 m/s

B = 4.9 m/s²

x(t)= - 4.3 t +4.9 t²

The velocity of the particle is given as

$V=\dfrac{dx}{dt}$

V=-4.3 + 4.9 x 2 t

V= - 4.3 + 9.8 t m/s

Velocity at point t= 3 s

V= - 4. 3 + 9.8 x 3 m/s

V= - 4.3 + 29 .4 m/s

V = 25.1 m/s

At origin :

x= 0 m

0 = - 4.3 t +4.9 t²

0 = - 4.3 + 4.9 t

$t=\dfrac{4.3}{4.9}\ s$

t=0.87 s

The velocity at t= 0.87 s

V= - 4.3 + 9.8 t m/s

V= - 4. 3 + 9.8 x 0.87 m/s

V= - 4.3 + 8.526 m/s

V = 4.226 m/s

a)V = 25.1 m/s

b)V = 4.226 m/s

0.001225 kg/L x 720 000 000L =?

I am Lyosha [343]

Answer:

0.001225 kg/L × 720 000 000 L = 882000 kg

Explanation:

Given:

The equation to solve is given as:

0.001225 kg/L × 720 000 000 L = ?

Let us write each term of the product in terms of power of 10.

As 0.001225 has 6 digits after the decimal place, therefore, we use the exponent 6 for 10 and the sign is negative. This gives,

$0.001225\ kg/L = 1225\times 10^{-6}\ kg/L$

Now, for 720000000 L there are 6 zeros after 720. So, we use exponent 6 but with a positive sign. This gives,

$720000000\ L=720\times 10^{6}\ L$

Now, finding the product, we get:

$0.001225\ kg/L\times 720000000\ L\\\\=1225\times 10^{-6}\ kg/L\times 720\times 10^6\ L\\\\=(1225\times 720)\times (10^6\times 10^{-6})\ (\frac{kg}{L}\times L)\\\\=882000\times 10^{6-6}\ kg\\\\=882000\times 10^0\ kg\\\\=882000\times 1\ kg\\\\=882000\ kg$
