In analyzing the data from your program, you discover one star that dims by about 0.1% for about two hours on every 63rd day. As

suming the dimming is caused by a single planet, what would you conclude about this planet?

Blake and Sandra are having a rummage sale. Blake drags 3 boxes a distance of 10 meters each. He exerts a force of 20 newtons on

vampirchik [111]

For Blake:

3 boxes at a distance of 10 meters each, each box weighs 20 N

Work done by Blake = 3 * 10m * 20N
= 600 J
Power = 600 J/ 2 min
= 300 J/min

For Sandra:

4 boxes, 15 N each at a distance of 12 meters each.

Work done by Sandra = 4 * 15 N *12m
= 720 J
Power = 720 J/ 4 min
= 180 J/min

Blake does less work than Sandra.
Blake's power is more than Sandra's.

A projectile's horizontal range on level ground is r=v20sin2θ/g. at what launch angle or angles will the projectile land at half

Ksju [112]

As given the formula of range is

$R = \frac{v^2sin2\theta}{g}$

now for the maximum range

$\theta = 45$

$R_{max} = \frac{v^2}{g}$

now for half of this maximum range we will have

$\frac{R_{max}}{2} = \frac{v^2sin2\theta}{g}$

$\frac{v^2}{2g} = \frac{v^2sin2\theta}{g}$

now from above we have

$sin2\theta = \frac{1}{2}$

so two possible values for above is given as

$\theta = 15 degree, 75 degree$

so above two angle we will have half of maximum range
