Negative - when the motorcycle displacement has a component in the opposite direction of the given force, that force is doing negative work on the motorcycle.
Answer:
The block will be move in to right side.
Explanation:
Given that,
Mass of block = 2 kg
First force = 3 N
Second force = 4 N
We need to calculate the acceleration
For first force,
Using newton's second law
Put the value into the formula
We need to calculate the acceleration
For second force,
So, we can say that the block will be move to right side because the acceleration is maximum in to right side.
Hence, The block will be move in to right side.
Answer:
The four fundamental forces magnitude and range are in order of Strong Nuclear Force > electromagnetic force > weak nuclear force > gravitational force.
Explanation:
The 4 fundamental force are weak nuclear force, strong nuclear force, em force and the gravitational force are discussed below.
Strongest force is the strong nuclear force as compared to all of them. It is very useful for capturing the atoms nucleus together despite the large repulsion which is occur between the same charges due to protons in the nucleus.
Electromagnetic Force is the 2nd strongest fundamental force. Magnetism and electricity was thought to be of 2 separate forces.
Weak Nuclear Force involves the W and Z bosons exchange. It has a very short range of
Gravitational Force is the weakest between all the fundamental forces. However, due to its long range it is the most dominant force. It follows the inverse square law like but it is always attractive in nature.
The linear expansion of iron is a = 1× 10∧ -5 /°C
Length edge is 5cm
Initial surface area of cube A = 6L ∧²
= 150cm∧²
The edge length of cube after being heated from
10°C to 60°C is
L = L[I +a dt] where the dt is = 60-10 = 50°C
5.0025cm
A surface area of the cube after heated is
A' = 6L' ∧²
= 150.1500375 cm∧²
The increased area is = A' -A = 0.15cm∧²
Answer: Explain the terms “criteria” and “constraints.” Criteria are things the design needs to do in order to be successful--its requirements. Constraints are limitations on the design. These may be materials available, the cost of the materials, the amount of time they have to develop the solution, etc.
