- Please answer this within 30 mins ! I will upvote !arrow_forwardA block of mass M is suspended at rest by two strings attached to walls, as shown in the figure. The left string is horizontal with tension force T2 and and the right string with tension force T1 makes an angle θ with the horizontal. T1 is measured to be 47 N, and θ = 50.0°. What is the mass of the block, in kg? Use g = 10 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.arrow_forwardCan you please help me with this question please? Thank you so much!arrow_forward
