Correct answer choice is:

A) Decelerate before the curve.


Explanation:

Decrease your speed before overtaking a curve. Watch out for road symbols signaling of nearing curves so that you have enough time to reduce down before driving through the curve. It is desirable to drive below the posted speed limit as you progress and drive through curves. Turn as little as probable.

If you have 4 kg of a sample with density of 1 897 g/ml what is the volume
Kaylis [27]
We know, Volume = Mass / Density
Here, mass = 4 Kg = 4000 g
d = 1,897 g/ml

Substitute their values, 
v = 4000 / 1897
v = 2.108 ml

In short, Your Answer would be 2.108 mL

Hope this helps!

To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newt
Firdavs [7]

Answer: A.E.

Explanation: To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newton's law of gravitation. The concepts of mass and weight are often confused. In fact, in everyday conversations, the word "weight" often replaces "mass," as in "My weight is seventy-five kilograms"

What is the momentum of a baseball with a mass of 4 kg being thrown at a velocity of 84 m/s towards the hitter
Delvig [45]

Answer:

<h3>The answer is 336 kgm/s</h3>

Explanation:

The momentum of an object can be found by using the formula

<h3>momentum = mass × velocity</h3>

From the question

mass = 4 kg

velocity = 84 m/s

We have

momentum = 4 × 84

We have the final answer as

<h3>336 kgm/s</h3>

Hope this helps you

A fisherman is fishing from a bridge and is using a "50.0-N test line." In other words, the line will sustain a maximum force of
umka21 [38]

Answer:(a) 50 N

(b)38.34 N

Explanation:

Given

Maximum tension(T) in line 50 N

(a)If line is moving up with constant velocity i.e. there is no acceleration

This will happen when Tension is equal to weight of Fish

T-mg=0

T=mg

Maximum weight in this case will be 50 N

(b)acceleration of magnitude 2.98 m/s^2

T-mg=ma

50=m\left ( g+a\right )

50=m\left ( 12.78\right )

m=3.91

Therefore weight is 3.91\times 9.8=38.34 N

23. Why would an astronomical unit not be<br> used to measure distances on Earth?
Rashid [163]
One Astronomical Unit is the distance between the Earth and the Sun, this acts as a sort of a cosmic metre stick. Astronomers don't and cannot measure distances. Distances are merely inferred from what actually has been measured, such as an angle, a relative luminosity, a time period
