Answer:
No. The sum of 2 and 4 is less than 7.
Step-by-step explanation:
So, first, to create a triangle, the sum of two smallest sides have to be greater than the longest side, which is 2+4 = 6, and 6 is smaller than 7.
So, no, 2, 4, and 7 cannot create a triangle, to be exact a right triangle.

Answer:
The acceleration of the train is 0.5m/s²
Step-by-step explanation:
Given
Velocity of the train = 10m/s
Time taken = 20 s
Required
Find the acceleration of the train.
The Acceleration if an object is the rate of change of the velocity of the object over time.
In other words, acceleration is calculated by dividing velocity by time.
Mathematically,
Acceleration = velocity ÷ Time
By substituting 10m/s for velocity and 20s for time, we have
Acceleration = 10m/s ÷ 20s
Acceleration = 10/20 m/s²
Acceleration = ½m/s²
Acceleration = 0.5m/s²
Hence, the acceleration of the train is 0.5m/s²
