Answer:

Direct relationship

Explanation:

A straight line graph can be referred to as a linear graph. This relationship shows that a change in the value of the dependent variable would cause a change in the value of independent variable at the same rate.

A straight line graph in a cartesian coordinate convey structure and represent stability.

Norma-Jean [14]

Answer:

0.528m

Explanation:

a)58.7 cm = 0.587 m

Let g = 9.8m/s2. When the frog jumps from ground to the highest point its kinetic energy is converted to potential energy:

$E_p = E_k$

$mgh = mv^2/2$

where m is the frog mass and h is the vertical distance traveled, v is the frog velocity at take-off

$v^2 = 2gh = 2*9.8*0.587 = 11.5$

$v = \sqrt{11.5} = 3.4 m/s$

b) Vertical and horizontal components of the velocity are

$v_v = vsin(\alpha) = 3.4sin(58^0) = 2.877 m/s$

$v_h = vcos(\alpha) = 3.4cos(58^0) = 1.8 m/s$

The time it takes for the vertical speed to reach 0 (highest point) under gravitational acceleration g = -9.8m/s2 is

$\Delta t = \Delta v / g = \frac{0 - 2.877}{-9.8} = 0.293s$

This is also the time it takes to travel horizontally, we can multiply this with the horizontal speed to get the horizontal distance it travels

$s_h = v_ht = 1.8*0.293 = 0.528 m$

The potential energy of a 40-kg cannon ball is 14000 J. How high was the cannon ball to have this much potential energy?

nasty-shy [4]

Pe = mgh.
14000 J = (40kg)(10m/s^2)(h)
h = 35 meters

<h3>Why did U.S. fight Gulf War?</h3>

The invaded of Iraq in Kuwait to gain the more dominance in the field of oil supply. The US and the UN Security Council requested that Iraqi ruler Saddam Hussein remove Iraqi forces from Kuwait in retaliation, but Hussein refused.
