7 0

Answer:

at least a day

Explanation:

Because when you have 6000 horsepower and 132000000 joules of energy it will take a little bit of time.

It would also be easier if you had the miles per hour

You are pushing a box up a ramp with 70 N of force. If the ramp is made steeper and shorter, what needs to happen to the box for

Elenna [48]

Answer:

A larger force than 70 N will be required for the box to continue moving

Explanation:

A ramp is an inclined plane surface that is tilted to form a slope on its opposite sides

A ramp provides mechanical advantage or force amplification, by allowing less force to lift heavier load from having to move through a longer distance to reach a particular elevation when the slope of the ramp is gentle

Therefore, when the slope is steeper, and shorter, more force than 70 N will be required for the box to continue moving.

Length of table is 1.0m,1.00m and 1.000m.Which one is more accurate?

natita [175]

Answer:

1.00 m is a more accurate measured length.

Explanation:

Denote length of the table by L.

For L=1.0 m, there is one significant digit after the decimal.

Care 1: When one more significant digit after decimal considered, the exact number can be from 0.95 to 1.05.

So, the possible span of error $\Delta E_1= 1.05-0.95= 0.1m$

For L=1.00 m, there is two significant digits after the decimal.

Case 2: When one more significant digit after decimal considered, the exact number can be from 0.095 to 1.005.

So, the possible span of error $\Delta E_2= 1.005-0.095= 0.01m$

Case 3: For L=1.000 m, there is three significant digits after the decimal.

When one more significant digit after decimal considered, the exact number can be from 0.0095 to 1.0005.

So, the possible span of error $\Delta E_3= 1.0005-0.0095= 0.001m$

As $\Delta E_1 >\Delta E_2>\Delta E_3$

So, the least error is in the third case when L=1.00m, hence, L= 1.00m is more accurate.

1. What are the different types of waves? Give examples of each type.

lyudmila [28]

Answer:

See explanation

Explanation:

1) There are two main types of waves;

Mechanical waves and electromagnetic waves.

Mechanical waves usually require a medium for propagation, e.g sound, waves on a spiral spring, etc

Electromagnetic waves do not require a medium for propagation e.g microwaves, x-rays etc

2) The phenomenon is known as refraction. Refraction occurs at the boundary between two media because of the change in the speed of a wave as it moves from one medium to another.
