Answer:

D. Water has a high heat capacity.

Explanation:

As we know that when water is used for coolant then in that case the water will absorb heat from the automobile.

here we know that the formula of heat is given as

Q = mC\Delta T

now here we know that

mC = Heat capacity of water

now if heat absorbed will be more then in that case when the heat capacity is more.

so here correct answer for more heat absorbed so that coolant will remove more heat from the automobile will be

D. Water has a high heat capacity.

Water is usually used to cool down automobile engines when they get hot, yes. Therefore, that means water has a high heat capacity.

That makes the answer letter D you provided above.

D) Water has a high heat capacity.

Another example would be trying to put out a fire with a bucket of water. Usually, you can put out the fire debating on the size!

(b) If the object is at 330 feet and its instantaneous velocity is 3 feet per minute at 30 minutes, what is the approximate posi
ELEN [110]

Answer:

The final position is 36 feet.

Explanation:

initial position, d = 330 feet

speed, v = 3 feet per minute

time, t = 30 minute

now the time is 32 minute

time interval = 2 minute

So, the distance in 2 minutes is

d' = 2 x 3 = 6 feet

So, the final position is

D = 30 + 6 = 36 feet

You attach a meter stick to an oak tree, such that the top of the meter stick is 1.87 meters above the ground. Later, an acorn f
Verdich [7]

To solve this problem we will apply the concepts related to the kinematic equations of linear motion. We will calculate the initial velocity of the object, and from it, we will calculate the final position. With the considerations made in the statement we will obtain the total height. Initial velocity of the acorn,

u = 0m/s

Also, it is given that the acorn takes 0.201s to pass the length of the meter stick.

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

Replacing,

1 = u(0.141)+ \frac{1}{2} (9.8)(0.141)^2

u =6.4013m/s

The height of the acorn above the meter stick can be calculated as,

v^2 = u^2 +2gh

h = \frac{v^2-u^2}{2g}

h = \frac{6.4013^2-0^2}{2(9.8)}

h = 2.0906m

Also the top of the meter stick is 1.87m above the ground hence the height of the acorn above the ground is

h = 2.0906+1.87

h = 3.9606m
