A stone is thrown upward at the speed of 20 m/s.How high will it be after 2 second?Take g=10m/s |
Answer» Given :-To Find :-
A stone is thrown up, so it MEANS it is currently going i.e it's the Initial Velocity and how much high it will go after 2 second,so we take time t and we have to find height Thus, FINDING how high the stone will go... → s = ut + ½gt² → s = 20 × 2 + ½ × 10 × (2)² → s = 40 + ½ × 10 × 4 → s = 40 + ½ × 40 → s = 40 + 20 → s = 60 Thus, the height is 60 m |

Body of mass 2 kg rests on the horizontal plane. Calculate the normal force acting on the body. |
|
Answer» Answer: The maximum static FRICTION, f s,max
=μ s
N=0.5×2kg×10ms −2
or, f s,max
=10N>2.5N, which is GREATER than the applied horizontal force. Hence, friction can impede the motion and the NECESSARY required frictional force to balance the horizontal applied force will be equal. Therefore, f=2.5N. please mark as BRAINLIEST and thank my ans. |

Answer» Answer: Types of Natural Resources: Renewable Resources: These are resources such as air, water, and sunlight that refill naturally. Non-Renewable Resources: These are resources like fossil fuels and minerals that do not restock reform very slowly. Biotic: These originate from living beings and organic material like plants and animals. Abiotic: These come from non-living things and non-organic material. These comprise air, water, and land as well as metals like iron, copper, and silver. Natural resources are also categories such as actual resources, reserve resources, stock resources and potential resources based on their development stage. Get the huge list of more than 500 Essay Topics and Ideas How to Conserve Nature and Its Resources? MANY of the natural resources are being used at a faster rate as compared to their SPEED of production. There is so a necessity for conservation of nature and the natural resources it offers. Here are some of the ways in which these resources can be conserved: Reduce Water Consumption Water is available in abundance on Earth. This is one of the reasons people do not consider much before using it. However, if we keep using it at this speed. In the future, we may not be left with as much of it. Therefore, simple things such as TURN off the tap while brushing or reuse the leftover water to water the plants can help in this direction. Reduce Usage of Electricity Use only as much energy as you require. It is thus advised to limit the usage of electricity. Simple habits such as turning off the lights before parting your room, turn off the electric appliances after use. Switching to energy-saving fluorescent or LED bulbs can make a change. Restrict Usage of Paper Paper manufacturing depends only on trees. Increasing the use of paper means encouraging deforestation. This is one of the key reasons for CONCERN is in today’s time Always ensure you use only as much paper as necessary. Stop TAKING print outs and use e-copies instead to do your bit. here is your answer hope it helps you |

Why current flows from anode to cathode? |
|
Answer» Answer: The CURRENTS outside the device are USUALLY carried by electrons in a metal CONDUCTOR. Since electrons have a negative CHARGE, the direction of ELECTRON flow is opposite to the direction of conventional current. Consequently, electrons leave the device through the anode and enter the device through the cathode. |
