Answer:

Earth's interior layers are ordered by density. The densest layer is the solid metal inner core, the mantle is of intermediate density, and the least dense layer is the lithosphere, particularly the continental lithosphere.

Answer:

They create enormous amounts of sound energy, much like explosion. When an aircraft passes through air, it creates a series of pressure waves just like the waves created by the boat. As the speed of aircraft increases these waves are forced to compress.

A placekicker kicks a football upward at an angle of 30 and a speed of 5.0 m/s at what other angle will he have to kick a second

Flura [38]

Answer: $60^{\circ}$

Explanation:

Given

speed of ball $u=5 m/s$

launch angle $\theta =30^{\circ}$

Range of a Projectile $R=\frac{u^2\sin 2\theta }{g}$

Range will be common for two angles i.e. $\theta [tex] and [tex]90-\theta$

for $\theta R=\frac{5^2\sin 2\cdot 30}{g}$

$R=2.209 m$

For $90-\theta$

$90-30=60^{\circ}$

$R=\frac{5^2\sin 2\cdot 60}{g}$

$R=2.209 m$

If a car has an initial velocity of 20 m/s and accelerates at 2.0 m/s² for 100 m, what is its final velocity?

WINSTONCH [101]

Answer:

28.28 ms-1

Explanation:

v² = u² + 2as

v² = 20² + 2× 2×100

v² = 800

v = 28.28 ms-1

05. The time required to complete one lap around a perfectly circular track having a radius of 1,835 meters is 86

likoan [24]

Answer:

v = 134.06 m/s

Explanation:

Given that,

Radius of a circular track is 1,835 m

Time required to complete one lap around a perfectly circular track is 86 seconds

We need to find the car's velocity. Velocity is equal to,

v=d/t

On circular path,

$v=\dfrac{2\pi r}{t}\\\\v=\dfrac{2\pi \times 1835}{86}\\\\v=134.06\ m/s$

So, car's velocity is 134.06 m/s.
