alexgriva [62]

Answer:

The value is $d = 31.45 \ m$

Explanation:

Generally the relative speed at which you are moving with respect to the person ahead of you is mathematically represented as

$v_r = v_s - v_c$

substituting 1.05 m/s for $v_c$ and 2.75 m/s for $v_s$

So

$v_r = 2.75 - 1.05$

=> $v_r = 1.7 \ m/s$

Generally the distance by which the person is ahead of you is mathematically represented as

$d = v_r * t$

substituting 18.5 s for $t$

$d = 1.7 * 18.5$

=> $d = 31.45 \ m$

What dose fixed supply mean? Tell what a fixed supply curve looks like and heat it’s appearance means

devlian [24]

Answer:

The quantity of some goods or productive factors is totally fixed, whatever their price, for example, there is only one Mona Lisa from Da Vinci.

Explanation:

Nature's original endowment of land can also be considered fixed. A rise in the price offered for land cannot create yet another corner at the junction of 57th Street with Fifth Avenue in New York City. A rise in the pay of famous athletes is unlikely to alter their effort. When the quantity supplied is constant at all prices, what is paid to use such a factor of production is called economic rent or pure economic rent.

When supply is independent of price, the supply curve is vertical in the relevant interval. The land continues to contribute to production regardless of its price. The increase in demand for a fixed factor only affects the price. The quantity supplied does not vary and the rise in price is exactly the same as the upward shift in demand.

When a tax is applied to a fixed good or service, it is paid entirely by (or "transferred" to) the supplier (for example, by the landowner), who absorbs it in its entirety, losing part of its economic income. The consumer buys exactly the same amount as before the good or service without costing mor

A student drops a 0.4kg ball from a height a of 49m above the ground. Neglect drag. Answer each of the following questions about

Elan Coil [88]

• The only force acting on the ball, and thus the net force, is due to its own weight, with magnitude

w = m g = (0.4 kg) (9.8 m/s²) ≈ 3.9 N

pointing downward.

• The ball is in free fall, so its acceleration is g = 9.8 m/s² (also pointing downward).

• The ball is dropped from a height of 49 m, so its height y at time t is

y = 49 m - 1/2 g t ²

Set y = 0 and solve for t :

0 = 49 m - 1/2 g t ²

t ² = (98 m) / g

t = √((98 m) / g) = √(10) s ≈ 3.2 s

• The ball's velocity v at time t is

v = - g t

so that at the time found previously, the ball will have attained a velocity of

v = - g (3.2 s) ≈ -31 m/s

and thus a speed of about 31 m/s.

ehidna [41]

Answer:

4. total energy

Explanation:

According to Bernoulli's principle at any two points along a streamline flow The total energy that is sum of pressure energy , Kinetic energy and potential energy of the liquid all taken in per unit volume remains constant. Therefore,

for ideal fluid flows through a pipe of variable cross section without any friction. The fluid completely fills the pipe. At any given point in the pipe, the fluid has a constant Total Energy.
