Answer:

Roundworms:

The size of roundworms ranges from microscopic to as long as a meter long. Most roundworms have a hard, sharp lance on their head, and some have bristles on the head. Most of the roundworms are protected by an adaptable yet solid, furrowed body covering.  

Roundworms are very primitive living beings, having no respiratory or circulatory system of a host. They have an empty body with two openings at the closures. Be that as it may, the head isn't particular or recognizable to the unaided eye.  

Roundworms reproduce sexually and can finish their life cycle in immature puppies, however as the little pupps immunity system develops (for the most part by a half-year-old enough), the larval phases of the roundworm will become captured and will encyst (become encased in a sore) in the puppy's muscles. They can stay encysted in the pooch's tissues for a considerable length of time or years.

You are travelling at 60.0 mph on the Grand Central Parkway near exit 10 where it is (nearly) parallel to the Long Island Expres
Romashka-Z-Leto [24]

Answer:

a)Vr= 5 mph

b)Vr= 115 mph

Explanation:

Lets

your velocity ,u= 60 mph

velocity of truck ,v= 55 mph

When object are moving in opposite direction the relative velocity  = u +v When object are moving in opposite direction the relative velocity  = u - v

a)

Truck is moving in the same direction ,so the  relative velocity

Vr= = u - v

Vr= 60 - 55

Vr= 5 mph

b)

Truck is moving in the opposite direction ,so the  relative velocity

Vr= = u+v

Vr= 60 + 55

Vr= 115 mph

A boy jumps from rest, straight down from the top of a cliff. He falls halfway down to the water below in 0.883 s. How much time
Salsk061 [2.6K]

Answer:

1.25 s

Explanation:

We are given that

Initial velocity of boy=u=0

Time=0.883 s

Let x be the total distance covered by boy in entire trip.

s=\frac{x}{2}

We know that

s=ut+\frac{1}{2}gt^2

Where g=10m/s^2

Substitute the values

\frac{x}{2}=0\times 0.883+\frac{1}{2}(10)(0.883)^2

\frac{x}{2}=3.898

x=3.898\times 2=7.796m

Again using the above formula

7.796=0(t)+\frac{1}{2}(10)t^2

7.796=5t^2

t^2=\frac{7.796}{5}=1.5592

t=\sqrt{1.5592}=1.25 s

Hence, 1.25 s passes during his entire tripe from the top down to the water.

A car is moving at 14 m/s. After 30 s, its speed inncreased to 20 m/s. What is the acceleration over time
Juli2301 [7.4K]

Answer:

0.2 m/s^2

Explanation:

initial speed 14m/s

final speed 20m/s

acceleration:

(20m/s - 14m /s) /30s = (6m/s)/30s = 0.2 m/s^2
