Answer:

A) Location of ancient climate areas

B) fossils of plants and animals

D) land features match up (like mountains) on different continents

E) magnetic strips in the ocean floor

Explanation:

location of ancient climate areas; fossils of plants and animals; land features match up (like mountains) on different continents; magnetic strips in the ocean floor

Continents are still continuing to move on their respective tectonic plates. The movement is very small, measured in mm and cm, but there is still movement.

If the velocity of a pitched ball has a magnitude of 47.0 m/s and the batted ball's velocity is 50.5 m/s in the opposite directi

Naya [18.7K]

Answer:

The magnitude of change in momentum of the ball is $97.5 m$ and impulse is also $97.5 m$

Explanation:

Given:

Velocity of a pitched ball $v _{i} = 47$ $\frac{m}{s}$

Velocity of ball after impact $v_{f} = -50.5$ $\frac{m}{s}$

From the formula of change in momentum,

$\Delta P = m (v_{f} -v_{i} )$

Here mass is not given in question,

Mass of ball is $m$

Change in momentum is given by,

$\Delta P = m (-50.5 -47)$

$\Delta P = -97.5 m$

Magnitude of change in momentum is

$\Delta P = 97.5 m$

And impulse is given by

$J = \Delta P$

$J = -97.5 m$

So impulse and

Therefore, the magnitude of change in momentum of the ball is $97.5 m$ and impulse is also $-97.5 m$

Three 500-g point masses are at the corners of an equilateral triangle with 50-cm sides. What is the moment of inertia of this s

Ede4ka [16]

Answer:

0.25 kg m^2

Explanation:

mass of each , m = 500 g = 0.5 kg

distance, r = 50 cm = 0.5 m

Moment of inertia about the axis passing through one corner and perpendicular to the plane of triangle

I = mr^2 + mr^2

I = 2 mr^2

I = 2 x 0.5 x 0.5 x 0.5

I = 0.25 kgm^2

During a tug-of-war, team A pulls on team B by applying a force of 1550 N to the rope between them. The rope remains parallel to

yawa3891 [41]

Answer:

3565 J

Explanation:

F = Force applied = 1550 N

s = Displacement caused by the applied force = 2.3 m

$\theta$ = Angle at which the force is applied = 0°

When we multiply force, displacement and the angle at which the force is applied we get work

Work done is given by

$W=Fscos\theta\\\Rightarrow W=1550\times 2.3\times cos 0\\\Rightarrow W=3565\ J$

The work done by team A is 3565 J
