Answer : a=10\ m/s^2

Explanation :

It is given that,

Mass of the engine, m = 30 kg

Thrust is equivalent to the force acting perpendicularly and it is F = 300 N

According to Newton's second law of motion :

F = m\times a

a is the acceleration of the engine.

a=\dfrac{F}{m}

a=\dfrac{300\ N}{30\ Kg}

a=10\ m/s^2

So, the acceleration of the engine is 10\ m/s^2.

Hence, this is the required solution.

Answer:

Acceleration, a=10\ m/s^2

Explanation:

It is given that,

Mass of the cart, m = 30 kg

Thurst applied to the engine, F = 300 N

Let a is the acceleration of the cart. According to Newton's second law of motion, force is equal to the product of mass and acceleration. It is given by :

F=ma

a=\dfrac{F}{m}

a=\dfrac{300\ N}{30\ kg}

a=10\ m/s^2

So, the acceleration of the cart is 10\ m/s^2. Hence, this is the required solution.

Water is used to cool down automobile engines when they get hot. Why is water used as a coolant? A. Water is a good conductor. B
Mrac [35]

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!

If a bust starts to move and its velocity becomes 90 km after 8 seconds . calculate its acceleration answer it quick please
kherson [118]

Answer:

a = 3.125 [m/s^2]

Explanation:

In order to solve this problem, we must use the following equation of kinematics. But first, we have to convert the speed of 90 [km/h] to meters per second.

90\frac{km}{h}*\frac{1000m}{1km}*\frac{1h}{3600s}   \\= 25 \frac{m}{s}

v_{f} =v_{i} + (a*t)

where:

Vf = final velocity = 25 [m/s]

Vi = initial velocity = 0

a = acceleration [m/s^2]

t  = time = 8 [s]

The initial speed is zero as the bus starts to koverse from rest. The positive sign of the equation means that the bus increases its speed.

25 = 0 + a*8

a = 3.125 [m/s^2]

A sound wave enters a new medium where sound travels faster. How does this affect the frequency and wavelength of the sound?
iren [92.7K]
The frequency doesn't change. If the wavespeed increases, then the wavelength must also increase ... It's just the distance the wave travels during each complete wiggle.
