It is actually answer's 1, 2, and 3. I just did the assignment.

1) They use equations to predict future weather.

2) They collect data from weather stations.

3) They draw weather maps.

The volume of a cantaloupe is approximated by Upper V equals four thirds pi font size decreased by 5 r cubedV= 4 3π r3. The radi
GuDViN [60]

Answer:

68.445 cm³/s

Explanation:

Given:

Volume, V = \frac{4}{3}\pi r^3

radius = 5.85 cm

Growth rate of radius = 0.5 cm/week

now

differentiating the volume with respect to time 't', we get:

\frac{dV}{dt}=\frac{d(\frac{4}{3}\pi r^3)}{dt}

or

\frac{dV}{dt}=(\frac{4}{3}\pi )3r^2\frac{dr}{dt}

now, substituting the value of r (i.e at r = 5.85cm) in the above equation, we get:

\frac{dV}{dt}=4\pi 5.85^2\times 0.5

or

\frac{dV}{dt}=68.445cm^3/s

hence, the rate of change of volume at r = 5.85cm is 68.445 cm³/s

a 100 g cart initially moving at 0.5 m/s collides elastically from a stationary 180 g cart. a) using the equation in the theory,
cupoosta [38]

A 100 g cart is moving at 0.5 m/s that collides elastically from a stationary 180 g cart. Final velocity is calculated to be 0.25m/s.

Collision in which there is no net loss in kinetic energy in the system as a result of the collision is known as elastic collision . Momentum and kinetic energy both are conserved quantities in elastic collisions.

Collision in which part of the kinetic energy is changed to some other form of energy is inelastic collision.

For an elastic collision, we use the formula,

m₁V₁i+ m₂V₂i = m₁V1f + m₂V₂f

For a perfectly elastic collision, the final velocity of the 100g cart will each be 1/2 the velocity of the initial velocity of the moving cart.

Final velocity = 0.5/2

=0.25 m/s.

To know more about elastic collision, refer
