A group of tourists drives through a state park in Maine. While arguing about whether the animal they've just seen is an Elk or

a Moose, a chipmunk darts across the park road. The driver, who was traveling 6.7 m/s through the park slams on their breaks and comes to a stop. If the car has an acceleration of -8.3 m/s2, how long does it take the car to stop?

Answer:

0.8 second

Explanation:

Given data

Speed v=6.7m/s

Deceleration = - 8.3m/s²

Initial velocity u= 0m/s

We can solve for the distance covered upon breaking the speed using the expression

v=u +at

6.7=0-(8.3)t

6.7=8.3t

Divide both sides by 8.3

6.7/8.3=t

t=6.7/8.3

t=0.8 second

How does distance from the equator affect the climate of an area?
AVprozaik [17]

Explanation :  

There are different factors that affect the climate of an area.The distance from the equator is one of them.

Equator is closest to the sun. The rays from the sun strikes mostly near equator and gets spread over the larger area. Hence, equators are much hot as compared to that of poles.

List 5 differences between a compound and an element.
Anuta_ua [19.1K]

Answer:

1.An element consists of the same kind of atoms while a compound is composed of different kinds of atoms.

2.A monoatomic element cannot be split up physically or chemically but a compound can be split up into new substances by chemical means.

3.Only limited number of elements are known in an element whiles number of known compounds are quite large.

4.The property of an element is the property of the atom whiles the property of a compound is quite different from that of it's constituents.

5 . Elements are represented by symbols and numbers.for example Sodium is represented by Na whiles compounds are represented by their chemical formula.for example,Salt is represented by the formula NaCl.

8. A 3.0 x 10' g nerf projectile is fired from a 1.5 kg nerf gun. If the velocity of the projectile is
tatuchka [14]

Answer:

v_g=0.2\ m.s^{-1}

Explanation:

Given:

  • mass of nerf projectile, m_p=30\ g=0.03\ kg
  • velocity of nerf projectile, v_p=10\ m.s^{-1}
  • mass of the gun, m_g=1.5\ kg

Now in this case the collision can be assumed to be perfectly elastic.

<u>For an elastic collision:</u>

m_p.v_p=m_g.v_g

where:

v_g= recoil velocity of the gun

0.03\times 10=1.5\times v_g

v_g=0.2\ m.s^{-1}
