O 0.33 m/s2
O 0.50 m/s2
O 1.33 m/s2
answer
0.33m|s2
Explanation:
v= 3.3m|s
t=10s
[tex]a = v \t[/tex]
=3.3÷10
=0.33m|s2

An object accelerates at 32 m/s² when a force of 71 N is applied to it. What is the object’s mass?
Answer:
2.21875 kg
Explanation:
FORCE = MASS x ACCELERATION so to find mass we divide both sides by acceleration. M=F/A
SO 71N/32m/s²=2.21875 kg.
remember N=kgm/s² so m/s² is canceled by m/s² the remaining is kg
The answer is mass= 2.21 kg
The first step is to write out the parameters given in the question
acceleration= 32 m/s²
force-= 71 N
The formula for calculating the object's mass is
mass= force/acceleration
= 71/32
= 2.21 kg
Hence the object's mass is 2.21 kg

How do you find the volume of a rectangular brick?
Answer:
Multiply the length, width and height of the brick to calculate its volume.
Explanation:
To find the volume of a rectangular brick, you need to multiply its length, width, and height.
The rectangular brick is 400 cubic centimeters (cm³).
The formula to calculate the volume of a rectangular prism (which includes a rectangular brick) is:
[tex]\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \][/tex]
Let's assume the length of the rectangular brick is 10 cm, the width is 5 cm, and the height is 8 cm. Plugging these values into the formula, we get:
[tex]\[ \text{Volume} = 10 \, \text{cm} \times 5 \, \text{cm} \times 8 \, \text{cm} \][/tex]
Now we can calculate the volume:
[tex]\[ \text{Volume} = 400 \, \text{cm}^3 \][/tex]
Therefore, the volume of the rectangular brick is 400 cubic centimeters (cm³).

What is created when domains align in certain metals?
Answer:
Generally, magnets are attracted to objects that are made of the metals iron, nickel, or cobalt. These materials are called ferromagnetic materials. ... When all or most of the domains are aligned in the same direction, the whole object becomes magnetized in that direction and becomes a magnet.

A lever has a effort force of 5 Newton's and an resistance force of 15 Newton's; what is the mechanical advantage of the lever?
Answer:
3
Explanation:
From the question given above, the following data were obtained:
Effort = 5 N
Resistance = 15 N
Mechanical advantage =?
Mechanical advantage is simply defined as the ratio of the resistance to the effort. Mathematically, it can be expressed as:
Mechanical advantage = Resistance /Effort
With the above formula, we can obtain the mechanical advantage as follow:
Effort = 5 N
Resistance = 15 N
Mechanical advantage =?
Mechanical advantage = Resistance /Effort
Mechanical advantage = 15 / 5
Mechanical advantage = 3

What is the average speed for Trial B?
m/s
Based on the calculations, the elapsed time and average speed for Trial B are equal to 3.0 seconds and 1.3 m/s respectively.
What is an elapsed time?An elapsed time can be defined as the difference between the final time and initial time that is required to complete a task.
For Trial B, the elapsed time is given by:
Elapsed time = Time (final) - Time (initial)
Elapsed time = 4.5 - 1.5
Elapsed time = 3.0 seconds.
How to calculate average speed.Mathematically, average speed is calculated by using this formula:
[tex]Average \;speed=\frac{Total\;distance}{Total\;time}[/tex]
Average speed = 4/3
Average speed = 1.3 m/s.

A student wearing frictionless in-line skates on a horizontal surface is pushed by a friend with a constant force of 50.0 N.
How far must the student be pushed, starting from rest, so that her final kinetic energy is 350 J?
Pleaseeeee
Answer:
Distance = 7 meters.
Explanation:
Given the following data;
Force = 50N
Kinetic energy = 350J
To find the distance;
We know that energy possessed by an object over a distance represents the work done by the object.
Mathematically, work done is given by the formula;
Workdone = force * distance
350 = 50 * distance
Distance = 350/50
Distance = 7 meters.

A rain cloud contains 4.2 × 10^5 kg of water vapor. How long would it take for a 4000 W pump to raise the same amount of water to the cloud’s altitude, 3.500 km?
Answer:
it will take 1,000.42 hours to raise the same amount of water.
Explanation:
mass of the water to be raised, m = 4.2 x 10⁵ kg
power applied in lifting the water, P = 4000 W
height through which the water will be lifted, h = 3.500 km = 3,500 m
The power applied the water is given as follows;
[tex]Power = Force \times Velocity\\\\P = FV\\\\P = ma \ \times \ V\\\\P = ma \ \times \ \frac{d}{t} \\\\P = mg \ \times \ \frac{h}{t} \\\\P = \frac{mgh}{t} \\\\t = \frac{mgh}{P} \\\\t = \frac{4.2\times 10^5 \times 9.8 \times 3,500}{4,000} \\\\t = 3,601,500 \ s = 1000.42 \ hours[/tex]
Therefore, it will take 1,000.42 hours to raise the same amount of water.

Krishne wants to measure the mass and volume of a key. Which tools should she use?
A. a balance and a beaker of water
B. a balance and a meter stick
C. a beaker of water and a ruler
D. a ruler and a meter stick
Answer:
A balance and a beaker of water!
Explanation:
Krishne wants to measure the mass and volume of a key. The tools that are to be used are – a balance and a beaker of water.
Mass will be represent with the amount of matter that is in an object. This will be measured in terms of kilogram. The mass can easily be measured with balance.
Volume is the quantity of matter that is in the object. This is measured in terms of cubic meter. If you drop the key in a beaker of water, the water inside the beaker will increase and this increases the volume of water that will be equal to volume of key.
