A block of mass 10kg is moved at a constant speed through a horizontal distance of 4m, by applying a force 50N. How much work ha
algol13

Answer:

Explanation:

given that

mass = 10kg

distance = 4m

force = 50N

to calculate the workdone when the force is applied in the same direction of displacement

mathematically,

workdone = force × distance

Workdone = 50 × 4

workdone = 200 joules

2) to calculate the workdone at an angle of 30° with the displacement we apply the formula

workdone = force × distance × cos Ф

workdone = 50 × 4 × cos 30°

workdone = 200 × 0.866

workdone = 173 . 2 joules

Write one example situation of Newton's Third Law involving mass that are the same.
puteri [66]

Answer:

Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.

Question 6
Margaret [11]

Limestone and dolomite are the rocks present in the locations which leads to the formation of caves.

<h2>Formation of caves</h2>

The type of rocks that once existed in these  locations are limestone and dolomite whereas the pH of the nearby groundwater is slightly acidic which is responsible for the formation of caves. Caves are formed by the dissolution of limestone due to acid rain.

<h3>Acid rain</h3>

Rainwater reacts with carbon dioxide from the air and percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone which become turn to form caves so we can conclude that Limestone and dolomite are the rocks present in the locations which leads to the formation of caves.
