<h3>Answer</h3>

Tools that magnify objects                   Tools that don't magnify objects

magnifying glass                                                  rule

telescope                                                            binoculars

microscope                                                    

   

<h3>Explanation</h3>

radio dish: is use to receive radio waves from the air.

binoculars: provide a magnified stereoscopic view of distant objects.

streak plate: is a technique which is used to grow bacteria on a growth media surface so that individual bacterial colonies are isolated and sampled.

wind vane: is used to determine wind direction.

ruler: is used for measuring a line.

microscope: is used to magnify the objects which are not visible by naked eyes.

magnifying glass: is used to magnifying tiny objects which are difficult to see yet they are visible.

telescope: use by space scientist to examine astronomical event that may take place in the sky which is too far.

Answer:

Tools that magnify objects:

1. Magnifying Glass

2. Binocular

3. Telescope

4. Microscope

5. Radio Dish

Tools that do not magnify objects:

1. Wind vane

2. Streak Plate

3. Ruler

Explanation:

The tools or devices that can show an object closer and bigger are called magnifying instruments. These tools have lens/mirrors or some other mechanism to make the incident light beams converge at one point and focus. If you notice, Magnifying glass, Binoculars, Telescope, and microscope use convex lens/concave mirrors which converge the light beams at one point. Thus they will magnify. Radio dish also converges the incident radio waves on the receiver. These might not visible to naked eye but magnification do occur in them as well with the help of a concave dish structure.

Rest other tools do not magnify any object as they don't have any such parts in them which can make the light beams converge at one point.

7. A 1000 kg car is rolling down the street at 2.5 m/s. How fast would a 2500 kg car have to
babunello [35]

1 m/s

Explanation:

To solve this question we use the following formula:

momentum = mass × velocity

momentum of the first car = 1000 kg × 2.5 m/s

momentum of the second car = 2500 kg × X m/s

To bring the cars at rest the momentum of the first car have to be equal to the momentul of the second car.

momentum of the first car = momentum of the second car

1000 kg × 25 m/s = 2500 kg × X m/s

X (velocity of the second car) = (1000 × 25) / 2500 = 1 m/s

A bicycle rider pushes a 13kg bicycle up a steep hill. the incline is 24 degree and the road is 275m long. the rider pushes the
Digiron [165]

Answer:

A. W = 6875.0 J.

B. W = -14264.6 J.

Explanation:

A. The work done by the rider can be calculated by using the following equation:

W_{r} = |F_{r}|*|d|*cos(\theta_{1})

Where:                

F_{r}: is the force done by the rider = 25 N

d: is the distance = 275 m

θ: is the angle between the applied force and the distance

Since the applied force is in the same direction of the motion, the angle is zero.

W_{r} = |F_{r}|*|d|*cos(0) = 25 N*275 m = 6875.0 J

Hence, the rider does a work of 6875.0 J on the bike.

B. The work done by the force of gravity on the bike is the following:

W_{g} = |F_{g}|*|d|*cos(\theta_{2})  

The force of gravity is given by the weight of the bike.

F_{g} = -mgsin(24)     

And the angle between the force of gravity and the direction of motion is 180°.

W_{g} = |mgsin(24)|*|d|*cos(\theta_{2})  

W_{g} = 13 kg*9.81 m/s^{2}*sin(24)*275 m*cos(180) = -14264.6 J  

The minus sign is because the force of gravity is in the opposite direction to the motion direction.

Therefore, the magnitude of the work done by the force of gravity on the bike is 14264.6 J.  

I hope it helps you!
