a baseball is pitched with a speed of 35.0m/s. how long does it take the ball to travel 18.4 m from the pitchers mound to home p
Vlad [161]
Given the speed and the distance, to find time you can use the formula speed is equal to distance over time. From there you can manipulate the equation for time to equal the distance divided by speed. Time is equal to 18.4 meters divided by 35m/s which equals 0.526 seconds.

Discuss a main factor negatively affecting species around the world and what scientist are doing in order to combat those proble
stiks02 [169]
These are the common main factors negatively affecting species around the world:

• Invasive species. The overview of non-native species into an ecosystem can intimidate endemic wildlife, distress human health and upset economies. Scientist solution contain making systems to avoid introduction of invasive species in the first place effectively monitoring for new infestations and fast abolition anew noticed intruders. 

• Over-exploitation. Overhunting, overfishing and overharvesting give importantly to the damage of biodiversity which is killing of numerous species over the past several hundred years. The solution is conservation and constant consciousness neighboring over-exploitation mostly poaching and overfishing. 

• Climate change. Alterations in climate over our planet past have altered life on earth in the long run which ecosystems have originate and left and species regularly go nonexistent. The solution must be reducing carbon prints and promoting education.

• Deforestation and habitat loss. This is a direct cause of extinction and loss of biodiversity. The solution is recommending stronger scientific forest protection laws. 

• Lastly is the pollution. Acid rain which is normally initiated by the burning of fossil fuels can acidify smaller bodies of water and soil harmfully affecting the species that live there by altering breeding and nourishing habits. The solution must combat atmospheric and hydrologic pollution.

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
